I'm trying to setup my 636. I was wondering what would be a good place to start with gearing. I want to still be able to ride in the streets. Should I drop a tooth or 2 in the front and some in the back. I'm a newbie and was told to just go bigger in the back and not drop any in the front. Any advice is very appreciated.

I was thinking going 54t in the rear.

 

ive had 2 of those bikes and ran +7 (50t) on both of them and cant imagine needing any more gearing for it. if i only rode parking lot i might do -1 +7 but thats it. now ill let some other ppl tell you how much they love thier 80 tooth sprockets.....

 

+1 sdfkillz... I run a 50T on my 636, and it's barely ridable on streets.. Definitely no riding on interstates, but it a haas in the lot so like he said, go with the 50T.. It's the best gearing I've found so far...

 

I guess I'll run a 50t. What will I be topping out at on the highway? is the 06 a 520 or 525 pitch? Any recomendations on where to get a chain and 50t sprocket?

 

why is it barely rideable? theres plenty of ppl running that gearing on the 03/04 636 with no problem riding streets and highways. you also have to remember a 50t on your bike is +10 and on his bike is +7 cuz the 03/04 stock is a 40t and the 05/06 is a 43t.
+7 removes around 18% of your top speed. all. 636's are stock with 520. pm sketchy on here, he'll hook you up real nice.

 

Cool, thanks. I'll hit him up asap.

 

We can certainly get you any size sprockets and chain you need, but will have a geared steel 525 50t going up tomorrow for $45 shipped with some other excess parts.

 

sorry, I already bought it from Sketchy. Thanks though!
