Took an old one up over the Himalayas. Two up. Over the highest road in the world. My avitar show me and my good lady crossing a glacier river!
Right hand gear change, with an extra lever to find neutral.
When going up the Khardong La (pretty steep) we were in gear 2 flat out for quite a long time it never missed a beat! Not that there was abundance of power but could still cruise at over 50mph on the level. Great fun, great bike but missed the power of my BM GS on the steeper hills. However I am no longer a boy racer or even an old croc racer!
I have looked at putting one in my stable as a run around. Lovely bikes - looks like a real bike- great sound.
