Report Mosten Raceday 2025, 29-30 august 2025

A sprint race on the 1/8 mile. The third race in the European Championship. STTG competed with 12 riders at the 30th anniversary of Mosten Raceday.

In the first qualifying round Jan Malmberg from Sweden completed his first run with a time of 5.26 seconds.

Arils Naess from Norway competed with Thorbjörn Ström`s old bike and showed with a 5.7 that he is an experienced rider.

John “Bübi” Hansen from Team Oakland Orange in Germany was able to start on his selfbuilt bike “Olga” with a time of 6.19.

Team Oakland Orange competed with a total of four bikes to mark its 15^th anniversary. All on a V-ROD Destroyer: Long-time member Horst Petersen scored a 6.25 and with their first race experience Thies Müller did 10.09 and Helga Buer a 13.7.

The leading Swede in the Championship Conny Karlsson started with a 7.11 in the game.

It was great to see Jörgen Godske from Team Big Dog Racing in Denmark back on the track with his Buell. He achieved an 8.17.

Sven “Hanson” Franzen from Team Top Speed in Germany did 10.14 in his first season on Gerd Caspari´s custom aluminium framed Buell.

Peter Niklas and Christian Bruhn from Team Sideburns in Germany also attended but couldn´t start in the first round because of technical problems with their Ducatis. Same problems faced Mogens “Monti” Jespersen from Denmark with Roman Sixta´s former blown Honda.

In the second qualification Conny Karlsson showed his qualities and impressed with a 4.76 and 242.26 km/h. Jan Malmberg also improved: 5.16 seconds. Unfortunately, Arild Naess was unable to start.

The chip they found suggested serious damage. However, we hope to see more from the sympathic team from Norway in the future.

Jörgen Godske improved to 7.58.

Rookie Thies Müller felt more and more comfortable on the V-ROD and achieved 7.66 and Hanson also improved and did 7.80 seconds.

Christian Bruhn was now able to race his Ducati and did 9.67. But the bike was not running very smoothly.

The unstable weather made all participants a little nervous, but Mosten was spared from thunderstorm except for a little rain shower, so a third qualification round could be held that day.

Thies Müller improved further to a 6.84 and Sven “Hanson” Franzen was also clearly enjoying himself on his bike finishing Friday with a 7.26.

Christian Bruhn did a 9.19 in his second run, while Peter continued to tinker and tweak.

Helga Buer was able to reach 12.58 in her first racing experiences with great support from her MC Ouzo´s.

Monti Jespersen also hoped to get his bike ready for the fourth qualification round on Saturday.

Jan Malmberg and Conny Karlsson were not able to improve their times but Conny did a personal best top speed.

The day went off without a hitch and the atmosphere at Mosten Raceday was so good that even the woman from the ambulance grabbed the announcer´s microphone and started the traditional “en, to, tre…Fisse.

Saturday, 30.08.2025

Only a few riders took advantage of the fourth qualification run on Saturday morning, wanting to save their equipment for the elimination round. Thies Müller became more and more confident and improved to 6.45. This put him on the heels of his teammate Horst Petersen, whose Destroyer refused to start. Helga had to withdraw due to a leak. Unfortunately Peter Niklas could not get his Ducati running and Monti Jespersen, after consulting the organizer, was able to complete his first run this season with his new bike, achieving a time of 7,98. However, he then dropped out due clutch problems.

A total of seven riders went into the elimination round. Jan Malmberg advanced to the next round with 5.18 and Conny Karlsson did 4.75 with his best top speed ever on the 1/8 mile of 244,68 km/h.

Thies Müller did 6.29 and Horst Petersen continued to ride very constant: 6.25.

Sven “Hanson” Franzen was delighted with a time under 7 seconds, but with 6.99 he did not make it into the final 4. Bübi Hansen with 7.79 and Christian Bruhn with 9.19 also dropped out.

So two Swedish and two German teams faced each other in the semifinals. Horst Petersen again drove steady 6.25 and Thies Müller did 6,360 this time. Then it happened that Conny had to go off throttle because he got too close to the barrier and finished his run with in 6.368 seconds. Jan Malmberg´s chain broke at the start, so suddenly two V-ROD Destroyer from Team Oakland Orange were in the final.

That is racing! A final run did not take place. Rain out.

So the 30^th Mosten Raceday ended with the 1^st place for Horst Petersen, 2^nd place for Rookie Thies Müller and 3^rd place for Conny Karlsson.

Congratulations to the teams and thanks to Inken and Jens-Peter Klinger, who took care of the pictures.

The last race of the season will be the spare race on 3.-5.10.2025 on the Airfield in Zerbst, Germany.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Mantorp Park, the last weekend of July 2025.

Eight topgassers came to race and seven made at least one pass.

Reigning topgas champion Conny Karlsson had some problems during the first few qualifications. Gerd Caspari did 7.5 on friday and another 7.5 on saturday in the other lane.

But during the last qualification Karlsson did a new personal best of 7.44 and was on top of the list on saturday evening.

Cord Albers only made one pass, he was busy for most of the weekend assisting Mecky on his blown Nitro bike.

Emmi Nordman qualified # 5 and got a bye run in the semi finals, because Albers did not show up.

Peter Niklas and Christian Bruhn arrived relative late at the 'four day event' at the legendary Swedish track. Peter's Ducati died after it's first burn out. Christian was unable to race at all, it turned out he outgrew his leather pants...

So Peter tried Christian's Ducati for a change. And he managed to qualify with it. But no more then that.

Sven Franzen is the new owner of the ex-Caspari AluBuell. Sven quaified #6 with it.

Jan Malmberg qualified third and beat Sven Franzen in the quarter finals.

Then Jan got sent home by Gerd Caspari in the semi finals. Gerd did 7.3 in tht run, his best of the weekend.

Karlsson did two more 7.4 second runs on sunday and met Caspari in the final round.

Gerd's bike ran out of steam, half way down the track. Conny's 7.7 was quick enough to win the race.

Next race will be in Denmark at the last weekend of august. Mosten Raceday is the race that is the most popular by the topgassers. So, most likely there will be a larger field of bikes. Some Danish riders, maybe?

Arild Næss from Norway is on the list.

Newsflash:

Tommy Karlsson raced in topgas in 2008 and has been helping Jan Malmberg the last few years.

Now, Tommy is the new owner of a Fast Cat powered Nitro Harley. Formerly raced by Mats Larsson. Tommy and Magnus will fire it up at Mosten, and hopefully make a few passes. And Mats Larsson is not done yet, he will modify his old topgas bike to run on Nitromethane during the upcoming winter.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The 2025 Euroserie Top Gas will kick off at the Mälardalen Open at Kjula Raceway, 2025-06-28 until 2025-06-29
The second race will be at the Meguiars Drag Festival at Mantorp Park, 2025-07-24 until 2025-07-27
and the third and final race will be at the end of august at Mosten Raceday at the Bode Engvej 15 in Denmark.

More news soon...

Just like in each season in the recent past, the 2024 Euroserie championship was decided at the last race, on the best 1.8 mile track in Europe, near Randers in Denmark. Ten topgas racers tried to qualify, below is the list.

Peter Niklas (above) and Tom Krause (below) failed to qualify. Both riders were absent, the last few years. It was good them both back in the saddle. Peter adjusted his wheelybar after the first round.

John Hanssen was the number three in the championship last year. This year in Mosten he qualified at place #8.

The last time we saw Jaakko Mietinen from Finland race at Mosten, he was on a V-rod Destroyer. Now he is back with a "Twin Cycle" topgas bike.

Horst Peterson was able to stay ahead of the other V-rod and of Jaakko.

Mike Dolata had raced the previous weekend in the Supercomp bike class in Hockenheim.

Herman Jolink is still refining the new dragbike with the Ducati Pangale engine.

Herman qualified at place#4, not a bad result at all for the veteran.

Jan Malmerg still had a chance to become the champion this season.

But his opponent Conny Karlsson was quicker in the qualifications.

Gerd Caspari had raced the weekend before at Hockenheim, where he sharpened his personal best.

And he became the top qualifier at Mosten.

On saturday morning the best eight riders made a pass and the best four would continue.

Herman Jolink leaned heavily to keep his bike at the right trail, but was not able to repeat his best time so far, and was out in the first round.

Caspari, Karlsson, Malberg and Mike Dolata continued.

Malmberg lost the breather of his catch can after the burnout in the semi finals, and was instructed to shut the bike off.

Gerd Caspari and Conny Karlsson advanced to the finals and Gerd won the race.

Conny Karlsson won the 2024 Euroserie.

Jan Malmberg (left on the picture) became the runner up, and Horst Peterson made third place, much to his own surprise.

Another great race at Mosten!

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Round two in the Euroserie. Mantorp Park

Three racers were present at the second STTG Euroserie race.

Herman Jolink with his Panigale-Ducati. Jan Malmberg with his blown "Derringer".

And Conny Karlsson on his Turbo-Harley.

A ceremony was held, to give Karlsson his award for winning Malmö.

And he also managed to win the race at Mantorp.

Qualifications were done on the 1/4 mile and eliminations were on the 1/8 mile.

There are seven topgassers on the list for the last race of the season, Mosten raceday.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The first round of the 2024 euroserie Supertwin top gas was held in Malmö at the 11th and 12 of May.

Nice weather on both days and the track was in good condition. Seven racers had voted in favour of that date, but unfortunately only four teams showed up.

Three rounds of qualifications were held on saturday, followed by two rounds of eliminations.

Jan Malmberg was the quickest on Saturday. He suffered wheelspin at the start during the semi finals, and a broken gearbox during the finals (sprag) prevented him from making a decent pass on Sunday.

Conny Karlsson qualified as the #2 on Saturday, and won the race on Sunday.

Malte Foit was able stay close to him at the first half of the track during the semi finals, when Conny had a bad start.

But Karlsson made no mistakes in the finals, won the race and set his best time and speed of the weekend.

Ole and Petra have sold their V-rod Destroyer, and Ole Schleichert is now in the saddle of the bike that Gerd Caspari, Bernd Niessen and Karsten Hormann have raced in the past.

He still needs some track time on it, and the eight mile strip at Malmö was a great place to get used to the bike and the routine that comes with it. Ole and made another pass after he got eliminated on sunday.

Times set during that weekend can be seen here...

The next race in the euroserie will be at the Meguiar's Drag Festival at the legendary drag strip at Mantorp Park, at the last weekend of July.
A four days event, a quarter mile race, a bigger field, and a few teams from Finland.

See you there!

Race #5 in the 2022 Euroserie supertwin top gas.
Nitrolympix, Hockenheim, 26-28 august.

There were five top gas racers on the entree list, Martin Buehler and Olaf Menzie from Switzerland, and Carsten Hormann, Gerd Caspari and Joerg Lymant from Germany.
A 4-field drag race was planned for sunday. The weather conditions were tropical.

Gerd Caspari had bought Serge Pinet's Buell and had sold his old bike to Carsten Hormann. The first qualification round was held on Friday morning. Gerd and Carsten were first in line. Hormann did 8.8 and Caspari 8.0 seconds.

Martin Buehler's bike spit out some debree when he left the start line, and did a poor 10.4.

Olaf Menzi was in the other lane, and his bike stopped shortly after the start.

Then Joerg Lymant did 7.5.

Martin Buehler and his helper Bend Foit had to wrench for the rest of the day, the other four racers went to the start line again on friday afternoon.

Hormann and Caspari could not improve their times, Lymant did another 7.5, slightly quicker then his first run.

Olaf Menzie had not been able to solve his problem. His bike stopped again, shortly after the start. Menzie did not come out on saturday for round #3. Martin Buehler had repaired his bike and did a nice 8.3.

Caspari left the start line way too early and did not set a time. Hormann and Lymant did not improve.

Round #4: Carten Hormann did set his best time so far, 8.76.

In the other lane Gerd Caspari improved to 7.51 and became the top qualifier for about five minutes. Last chance to qualify for Olaf Menzie, but again the same problem. And Martin Buehler was not able to reach the finish line. Then Joerg Lymant set things straight with 7.38.

Carsten Hormann did 8.78 in the semi finals. But he was sent home by Joeg Lymant, who sharpened the topgas class record to 7.36. Then Gerd Caspari caused an upset doing 7.27 and 298 KmH.

Martin Buehler disappointed with 10.2 seconds.

The final race could have been exciting, but Gerd Caspari's bike stopped right after the start, while Lymant did 7.4 and won the race.

Below are Gerd, Joerg and Carsten.

Joerg Lymant also secured the 2022 Euroserie championship at Hockenheim.

Martin Buehler and Jan Malmberg need to decide at Mosten who will become the runner up.
Gerd Caspari became Europe's quickest topgas biker ever, at the the semi finals at the NOX, but his bike suffered major damage.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Race #6 in the 2022 Euroserie supertwin top gas: Mosten Race Day at the Bode Engvej in Denmark. The last race of the serie.

There were 13 topgassers on the entree list, but not all of them showed up. Still it was the biggest field of the season. Nice and sunny weather and a great atmosphere. Like always, the 1/8 mile "Custom Cycle Raceway" was in excellent condition.

Two qualification rounds were held on friday, and the best eight would advance to the eliminations on saturday.

Olaf Menzie was the first topgasser on the track.

But his bike did not perform the way it should be.

Neither did Martin Buehler's bike.

6.12 second for Horst Petersen on the V-rod Destroyer.

Cord Albers on an NCCR-Buell.

Malte Foit's engine is similar to the one in in Albers's bike.

And Malte was slightly quicker then Cord in the first round.

A nice 60 foot time for Jan Malmberg, but no more power after that. The problem seems to be a damaged piston, just like at Mantorp, earlier this season.

Another nice pass by a V-rod Destroyer, John Hansen was not as quick as Petersen, but good for the third place that morning.

Carsten "Mecky" Hormann was at the podium at Hockenheim, and became the quickest after round one in Mosten.

Martin Buehler improved in the second round and went from the bump spot to place #5 in the list.

Malte Fiot also did better in that round.

A nice launch for Cord Albers in the second round, but his bike broke down shortly after that, and the race was over for him.

Both Petersen and Hansen did better in this round, and Hansen managed to stay ahead of Menzi and Buehler.

Hormann did 5.44, and dropped to #2 on the list.

Anders Jensen came out for the first time.

But it is not clear what time he did. Anders was also coaching his crew members that were successful in other classes.

Olaf Menzi was able to improved his time, but was passed by Martin Buehler in the ranking.

And by Joerg Lymant, who became the top qualifier.

On saturday morning, the eight quickest were to battle it out, but only five came to the start for the first round, de four quickest would advance.

Petersen opened with a poor 6.9. Malte Foit was next, he should be able to beat that time, but he could not.

Consistent runs for Hormann and Lymant, and Martin Buehler also advanced to the semi finals, where Petersen produced his best run of the weekend.

Mecky Hormann had a bit of a wild ride but managed to go quicker then Petersen.

Martin Buehler did not come out, and Joerg Lymant produced another 4.7.

The seat of Hormann's bike was damaged beyond quick repair, so he did not race the final round. So Joerg Lymant could take it easy, he used 4.9 seconds for his last run at Mosten.

Below is the podium of Mosten, Mecky Hormann on the left, Hort Petersen on the right side, and Joerg Lymant, the 2022 champion, in the middle.

Jan Malmberg is the 2022 runner up, Martin Buehler was not able to pass him during the last race, Martin became the #3.
