The reason I got the R65 Mono was to get down to one road bike, so it had to cover many tasks for me...and it does. I can no longer afford to keep several road bikes to pick and choose from, I change my R65 to suit my needs at the time.
My other bike is a 1987 Honda TLR200 that I sometimes use in Twinshock Trials, I've had it for over 10 years now. Otherwise, a shed full of projects.
