I've been told they give a big boost to speed so have set my mind on getting one, I wanted to fit it myself but first need to know a couple of things..
Whats the difference between a Primary and Secondary gear kit - if you want the secondary do you first need the Primary?
What would be the best place to purchase one
Are they easy to fit, could anybody give instructions?
It would help me soo much I've searched everywhere but cant find anything on them
I have a Yamaha Aerox 50 '03 plate if anybody wonders
Thanks, George.
