Hi, I was wondering what gearing people were running on RX125 Yamaha's on Kart Tracks.
Mine currently has a 13 tooth front and a 38 tooth rear. I'm getting up to about 80 - 90 kmph
at the end of the straight on our local track. I'm only just hitting fourth gear.
I was wanting to make it a bit lower geared to get a bit more get up and go.
But I'm not sure what size sprokets to go too. Any suggestions?
Cheers
Muzza
