i have an 07 gsxr 750 and am looking to start stunting but yet have a good streetable bike that i can do circles and 12 o clocks on. if i just throw a 56 tooth on the back am i going to be good to do this?

 

if your rear is a 47 i would prob go up 8 in the rear you could go 10 but its going to tack high for the street but it wont be to bad

 

my rear is 45 i just want to street ride but yet do circles and 12's

 

yea i would go up 8 in the rear

 

10 is pretty standard but 8 should be fine. It'll help keep the revs slightly lower

 

so taking my 45 to a 56 would let me street ride and yet get good slow stunting?

 

Yeah, that's fine and real common. Your revs will be higher, but especially around town it won't be bad.

 

I'm rockin -1 up front and +2 in rear on my 07 gsxr 600. Works out fine. You can do "circles and 12" on stock gears honestly.

 

whats going down one in the front compared to in the back because i hear that going down one in the front is like going up three in the back. is there any truth behind that?

 

Its exactly what you said. It basically is going up 3 in the back if you go -1 in the front. I don't know of too many people that go more than -1 in the front.

 

I ran -2, +15 on a lot bike I hade (05 gsxr 600) but I have heard that too little teeth on the front causes ALOT of strain on the engine and tranny. I like doing a stock front and going big on the back personally, stays smoother at idle. But -1 doesn't seem to hurt any eigther. Most people -2 in the front and only go a few up in the back so that don't have to get a longer chain.

 

money in the bank

 

Starting with a stock front is a good idea. In the future should you ever decide you want more or less gearing you can replace the front sprocket inexpensively for a +3/-3 gearing. Changing the back to do that is obviously more expensive especially if you need a new chain.

 

i love my -3 front !!!!!
