I'm telling you that when a bike is leant over cornering the switch will be in exactly the same position as when the bike is upright going straight. -- Clem

Another potential problem, at least to me, is that I might wll want to use a turn signal, say to the left, but actually and physically travel exactly straight on. As in main road sweeps to the right, smaller road goes straight on. I know it's (wave to betty!) silly, but I like being able to switch blinkers on or off when I want them on or off. regards, CrazyCam

Fair enough, but there was some bike I rode with them and it was ages ago. It wouldn't have been the XT250 or the VF750 or the VF1000R and ceratinly no any after that. The RZ was the only one I could not write off as having them. Maybe I was riding a mate's bike or something?

They turned off after 40,000 kms? Helen's V65SP had tail-lights that turned off after about every 1000 kms, but I fixed that by packing the light fitting with foam. Theo |
