Just got my 15 tooth sprocket in a couple of days ago, haven't had a chance to test it out until last night. Have to say, lost a bit of the good ol' acceleration, but getting it onto the highway and being able to stay at 110kph without breaking 7k rpm is nice, very nice...

will be interesting to see how it handles on the rough, it MAY have lost a bit too much power, in which case the 14 is going straight back in...

 

stock chain?

 

yup, would an aftermarket make much of a difference?

 

nope.

 

Wow, 15 tooth sproket and it can with stand about 70mph. Mine on stock gearing can barely manage 70mph, but it can do it, just gotta be a flat road, no wind day.

 

oh, yea, forgot to mention I have to drop down a gear on nearly any rise I come to... ah well, reminds me I'm still on the bike...

 

you have to mod anything to get it to fit. i want a 15 so the long trips aint so bad.

 

I've held over 80mph on flat roads and I weigh 220.

Don't know what could be wrong with your bike...

 

I haven't done anything else. May have issues with the chain length, mine was just slack enough to fit it without a new chain. Also recommend having an experienced motorbike mechanic help you, theres a few hard bits (took a full charge of air to get the nut off...)

 

Thanks for the update. Keep in mind that at 68mph indicated you're really only going about 59 mph. I've seen it off by 7-9 mph on the highway.
