When you change the weight distribution of the bike, it does affect the stability to a certain extent. I think that what you experienced had more to do with the lack of leverage with your clubmans vs the stock handlebars, which are much wider and therefore require a different amount of movement to make steering corrections, particularly at low speeds. This is hard to get used to, and isn't exactly intuitive.
does a cafe conversion make a motorcycle less stable?
i have a CL360, very similar to a CB350 twin.
I put clubman bars on it (yeah i know....they're gone now..bent to sh*t). i shifted my shifter back and had the back footpegs being "rear-sets". when doing this most of my weight is shifted over the back tire.
when riding, having your weight moved to this position on such a small bike, does it make it less stable or more likely to go down?
I hit a rock at 3mph at a stop sign the other day, and it locked up under my front tire and the bike immediately started to fall.
i tried to catch it, but i was by a construction zone and my feet slipped on all the damn dirt on the ground.
needless to say i was pissed. anyways, i never had that issue arise in a different riding position on my other bike (cx500). i am sure most of it is complete rider (dumba**) error due to me being inexperienced in this new position. but i have to wonder to.
