Lmao.......I dont pay any attention to the one in hire cars I have let alone one on the bike hehe............but Im sure they'd be helpful for some reason.
Personally I just go up until I cant go up anymore....and when I stop I go down until I cant go down anymore lol....what happens in between is decided on the sound of the engine hehe (if its screaming I go up...if its nearly stalling I go down) but hey I am just an 'old woman' so what the hell do I know ;D ;D ;D ;D ;D

I dont think Id benefit from a gear light/number thingy somehow hehehe ;D ;D ;D
