Not sure how I feel about that children's trials bike. I'm glad to see the OSSA brand back but that effort is kind of lame in a lot of ways. Vintage trials is coming on strong, I hear in Europe the vintage events are getting bigger turnouts than regular events. I'll say it again: Bring back the MAR with a plastic gas tank and a better clutch. BOOM! DONE!

I have a hunch that the electric trials bike market will soon be flooded with various makes and models. I hear that Yamaha has invested in EM to boost production. I think to bring an electric bike to market could be a tough thing for OSSA. I think they would be better off going the retro route and bring back copies of the old models, imagine a MAR with a modern clutch or a Phantom with a modern exhaust pipe. Capitalize on their past. No one can do that but OSSA.

Update: I got the O.K. from our association president to use my half helmet. I think because I'm riding the easiest sections that may have been a factor in his decision. Thanks for everyone's input.

Thanks for the replies. Seems like one vote "NO WAY", one vote possibility "YES" and one vote "you'll look weird". I will consult with my association Thanks again.

Would a "half" helmet be accepted at a trials competition. The kind that just cover the top of your head. I use one for practice and really like it. It is DOT approved. I'll be riding in the lowest skilled sportsman class.

Thanks, I'll take a look. There is a very short shoulder on the original sprocket.

Is there anyone who sells the 11 tooth MAR sprocket in the United States?

Thanks so much! Lots of good information there!

What are gear ratios for a 5 speed 250 MAR? Thanks.

Thank you, that chart is very helpful. I have saved it to my favorites.
