i've been looking into changing my chain and sprockets. i know a lot of you have great setups and i want to hear your opinions. i've been riding for a year now and got about 10k miles under me. i want to do a couple track days a month maybe but keep it good for the streets. if you guys could explain the -1(front?)/+2(back?) and let me know the best size for you as well i'd appreciate it big time! from the info i search on this great forum i got my size is 14 and 45 (sprockets maybe). and i want to keep the chain stock at 525. again, thanks in advance guys :thumbup:

it should list your stock sprocket sizes and let you know all the differences in changing your sprocket.

Basically the -1/+2 refers to going 1 tooth smaller on the front sprocket and 2 teeth larger on the rear sprocket. This is similiar to changing the rear end gears in a car as it adjust what rpm you will be at given a certain speed in a certain gear.

The -1/+2 combo will give you a lot more low end grunt but you will sacrifice some top speed (nothing that is really needed, IMO).

However, good luck on keeping a 525 chain unless you buy all OEM parts. I checked every vendor on as many boards as I could find and attempting to get 525 chains and sprockets was either impossible or just really expensive. I would just switch out everything and go to a 520 set up.

cool, thanks man! how off is the speedo after this mod? is it really noticable? so this mod helps benefit "SOLELY" low end? thanks for your help man!

Yes it will be very noticeable. Gearing commander can show you the difference in numbers. I had a -1 in front on my last bike and up around 90 or 100 it was about 15 or so mph off. You can buy a speedohealer to correct the problem though, its about $100. So if you do change sprocket sizes I would include an extra $100 in the price.

Yes, most people do it to shift the power band to more streetable rpms. However, if you wanted to go larger in front and smaller in back in theory it would be the opposite, less low end power and more top end mph. In actuality I doubt your bike would have enough power to actually use the extra gearing at those speeds.

Take into account if you do a lot of commuting (I do) then you will be running higher rpms at the same speed thus your mileage will take a bit of a hit. Not sure if that is important to you or not, but another point to consider.

does it consist of just taking the plastics off and it's staring at me after that? i feel dumb for asking. i'll just take a look at it when i get it in. im gonna do a 520 chain with a -1+2 and get a speedo healer then. i think that's the best setup you guys have. thanks for everyones help. keep posting, im still learning!

FYI, when you go to pull the large nut off that holds the front sprocket on it helps to have an impact wrench to break it loose.

When looking at sprockets your front is going to be steel and your rear is probably going to be aluminum, make sure the rear is a hard anodized aluminum or else it will rear really fast.

www.motomummy.com is having a good sale on a chain/sprocket kit right now too. I have it and haven't had any problems so far.

I went wit a vortex sprocket +2 in the rear wit the stock 525 chain and yes they have a -1 available for the stock chain so you could stick wit the 525 if you wanted
