RACE GEARING QUESTION - SV650.org

27-01-05, 04:59 PM

Can anyone recommend a good sprocket setup for the race track? I am going to primarily run Sears Point, Thunderhill, and Buttonwillow with the AFM. I have the stock ratio now and was thinking about dropping some teeth on the rear sprocket. ANY SUGGESTIONS? ANYONE RUN THESE TRACKS? Any help is appreciated.

I dont race on track but i found 46T rear really made a huge difference comming out of the corners

I'll second that... A 46 tooth back sprocket is a great mod!!!

On my race bike is use a combination of:

14 or 15 front
44/45/46 rear.

Gearing is a personal thing and not knowing what those tracks are like id start with the standard setup and then spend a day testing the different combinations. Obviously a 15/44 would work at a track with long straights and a higher corner speed. 14/46 would be better for short twisty tracks that need grunt from the corners.

try the standard and then gear depending on whether the bike is revving out at any point. If your flat in top and need more top end then drop a tooth off the rear. But some people use only 4 or 5 gears and not six..so best is to book a test day at a fairly flowing circuit that has all the variables and go from there.

Then again some people racing in the same series as me over here have run the standard gearing all year...and had plenty of top five finishes...

SV Racer I was asking about changing the front sprocket and keeping the rear as standard simply because it seems less hassle What would you recommend for A and B roads with as many twisties as I can find but still keeping a top end in the 120 region

drop to 14t on the front sprocket but IMO the rear sprocket is not that hard to do plus you can have a shiney gold one which people can see and that will always make you faster.

Chris, I suppose you are probably right as I have a copperK3 with goldie engine bolts,at least it will all match Now looks like a copper/black and gold SV

If you put a smaller sprocket on the front you put a lot more strain on the chain whereas on the rear it won't make any difference and it's also easier to do. You'd be more than happy (I suggest) with a 46 tooth rear.

The only problem with lowering the gearing is that you're forever trying to change up into seventh

Not knowing the circuits, its hard to say. If you're after the least possible hassle, go for 14/45 and maybe change to 15/45 for the tracks with very long straights.

This works ok for most tracks over here, but a 44 would be good for some tracks. If you get hold of a second sprocket hanger, then changing them is a piece of ****.
