A fellow Can-Am Rider.
That explains your Ski-Doo habit, once you ride Rotex its hard to leave. NOBODY makes the torque like Rotex.
I've had a couple of'em 250 + 350 quilifier
A bud still has the last year 87, 500 MX, (to me it looks like an enduro model, its got headlight and wanna be tailight) its all white body work with red seat, pinstriping and grips.
I'll havta dig out some pics.
We did a vintage motorace back in 93, for BikeWeek over here in june.
I rode a 73 Alloute 125, sounds like (allowet), Canadain bike.
and a bud rode a Hercules 175 in the open.
He also had a BULTACO,Alpeina.
Those are ballsee bikes, couldnt believe the power coming out of 'em.
He got brave and to the Hercules off a 6' jump and did a table top.
WELL you know how he land'ed THUMP,then wrench his nuts on the tank, about p__sed myself I never laughed so hard in my life.
Still can't see why there were'nt more deaths riding those things.

Ya had to be a true rider.
