Guys, I need to know what gearing ratio's is used at T.G.P., I am finishing my Supermono( xr628 motor in a TZ frame) and need to get a headstart on gearing. Thanks, DARRYL

I ride a SRX 621 with 14/40 gearing. Seems to work pretty well. I hit 8 grand by the end of the back strait. If you are running higher RPM you might want to try a 15/45 first. That puts me at about 9K max. Depending on the internal gearing of the Honda you should be about 110-115mph at top speed. Doesn't sound like much but try carring all that through the sweeper and you may need the seat recoverd after the race :EEK:
