Hello, I'm new to this forum and didn't want to search through all the threads. I have a 2002 CBR 954 RR and currently have a 15 front sprocket and 45 rear sprocket. I spun 4 teeth off of my rear sprocket with a loose chain. I'm thinking about upping my rear sprocket to 54 but keeping the same size front sprocket. I am also doing a 520 conv. and am concerned about the cc rating on the chain. I want more torque for wheelies and stunting and was wanting ADVISE or CONCERNS about this drastic jump in sprocket size.

Thanks in advance for all the posts.

Walker

It will be a wheelie machine, as if its not already but youll be pulling 4th gear wheelies. You will loose quiet a bit of top end but the 520 and sprockets will be good for you since you want to stunt.

Taken from HAI Bikeshop's website:

520 has the advantage of being lighter weight and increasing performance just from the loss of rotating mass. However, the thinner profile does have a shorter life expectancy than a thicker 525 or 530.

(Increase in rear sprocket teeth)

+5 – Provides a good place to start for anybody looking to get a little more into the stunts without sacrificing street riding or too much top speed. Will gain some torque/acceleration while losing roughly 10% of top speed.

+10 - Provides good amounts of power for slower wheelies while still having decent street riding. Will gain good torque/acceleration while losing roughly 20% of top speed.

+15 – Provides great power for technical slow wheelies. Street riding will be reduced to moderation in the city limits. No highways. Will gain great torque/acceleration while losing roughly 30% of top speed.

+20 - Provides huge power for anything and everything technical. Street riding will be reduced to just parking lots. Not for beginners. Will gain huge torque/acceleration while losing roughly 40% of top speed.

+25 or bigger – Ridiculous… but fun. Go big.

Beware of first gear with your new sprocket!

stunting will take alot of abuse.. so get steel sprockets and a good chain.. also what speed do you want to do wheelies..stunting.. the slower you wanna go.. the bigger you go in rear sprocket.. i did the -1 +2 first.. then went to a -1 +5 .. to make it a 48 in the rear. .i did stand up wheelies in 4th gear.. but also limited my top end quite a bit..

so what speeds do u wanna be at

I just went -1 +2 this year, i only got to ride for about 50 miles. I would have to say for my riding its about perfect, although just -1 would be just fine too. Highway wheelies at 65-70mph in 4th gear are super easy now and good control, i think going any more though would be silly, at least for me.

I've been riding my 954 for about 3 years now and have had a hard time trying to pull 3rd gear wheelies with my -1 +2 for some reason. I want to be able to pull wheelies at slower speeds and be able to pull them up in higher gears at faster speeds. I haven't bought the sprockets yet but am still concidering the 54 rear, but I may end up only going up somewhere between 5-10. So keep the input coming and I thank you guys for all your knowledge.

Walker as far as making your gear choice i will just state that -1 +2 will for a fact wheelie 3rd gear (sitting down). You will have to be a little higher in the revs then 1st or 2nd gear, but it will go up. Now if your havin trouble you could add another tooth or 2 in back, but your gonna lose more top end. You know how you ride and if thats acceptable or not, but in case there was doubt about the gearing i just wanted to point it out.
