Hi Everyone,
This is my first post and I hope some of you can give me some helpful advice.
I have bought Speads RS08 with a 1300 Hayabusa engine. It has a manual shifter with a Flatshifter.
I would now like to install a paddle or button shifter and have looked at a number of different systems some fairly reasonable and some really expensive.
Flatshifter has a good system of paddles with electronic shifter and I have also looked at MPS but these use air bottles.
What do you guys think?
