thought I had stock gearing but its 15/41! now what?

[thebugslaaaa]

Hey guys, I just took my rear wheel off for the first time and it looks the the PO put a 41 tooth on the rear. I have been having problems getting the front wheel up and I'm hoping this is part of it! I was thinking of going to a 47 but am now worried because I thought my 41 was stock gearing haha. I am thinking of maybe just going to a stock 44 and seeing how I like it? I was really set on a 47 rear but feel a 6 tooth increase may be too much. Any insight?? I would like to still be able to cruise 70-75 for short bursts on the highway as well.

S model ? The SM runs 15/41 as stock....

[thebugslaaaa]

Doh! I knew that. forgot about them smaller wheels! haha ok so in that case, what would you recommend to get a little more torque out of her but still maintain "street-ability" 15/44??

43 in the rear is a good mid choice. Then you can opt for 13-15 in front depending on what riding you plan on doing. Works for me. 13 for technical trails 14 for faster off road, 15 if you ride alot of asphalt but still get off road. That's for a DS. SMs may run a lot different gearing?

I run 14/41 on my SM but find the gears way too short but it works okay. This combo is roughly the same as the 15/44 you are suggesting. At 75 miles an hour you will be hitting about 8k RPMs

wow 3 teeth really kills the top end that much?? I can hit 100 mph on my stock 15/41 gearing... hmmm trade offs eh?

When mine was std I did the same thing and went to 15/44 on my SM . The 41 just seemed to much for the std motor and it had very little go down low . The change of rear sprocket helped , but it wasnt untill I put in the big bore that the bike ran the way I wanted      ( heaps of grunt ) . I think in std form the motor is just too underpowered for the weight of the bike , if you can afford it do the 50 hp package and it will rip , greg

I have an S model. I run 14/44 My friend (same bike) runs 15/47 geraing is practicaly identical. Just go a tooth smaller in the front. Front sproket is only abt $20. thats not much of an investment if you dont like it...

I run 14/41 and top out at 90-95. Cruise at 80 no prob.

A lighter flywheel, FCR 39mm carb, MRD Exhaust, K&N air filter, 3x3 airbox mod, Cams, and a Big Bore kit. I run 15/39 gearing, but, I don't do wheelies. With this gearing, going 70mph (not on Interstate Roads) is very comfortable, the engine is not "working" too hard, less shifting, less engine braking, and I'm sure with the proper amount of throttle/clutch technique, you could be on your ass asap !
