Air Cooled Mono Build

Featured Replies

I’m thinking of building a air cooled mono. I have an extra rebuildable Rotax 280 trials engine and exhaust. Just need a mono chassis. Any recommendations?

Old Beta TR34 chassis, or JCM's chassis would be a good starter.

JCMs , you can't give away at the moment, if you can find one, so a good cheap option. If not what about a TY mono chassis, loads around and possibly easy modded!

I wonder how much different my engine mounts compared to a Aprillia Climber?

Bottom half the same, no problem. Climbers engines can be converted to air cooled.

Thanks! That’s good to know! I had a early nineties 280 Climber and remember the bottom end was similar.

I’m from the States, I’ve never heard of JCM?

It's a French make, only for a couple of years, never really took off, and not overly popular. Nice looking and good spec, avoided now as too limited to get spares etc.

dont use the Aprilia frame, that would just be a rebuild with another engine. Make a mono special, something individual and unique!
