Chain-Sprocket Combo?

[Bearusa]

I do hate to ask a redundant question, but I don't know the proper measurements and I'm hoping one of you guys will. I have a '12 Busa with a 46T rear sprocket and a chain that's stretched and long overdue to be replaced. What I'd like to do is change out the whole set and go with 17/46 or 17/47 gearing. The question is about how many links will be right for the chain? Will the stock 114 links fit by going down 1 tooth in the front and up 3-4 teeth in the rear?

I believe it will. But you can easily check it to make sure before you mushroom the rivet.

17/47 is pretty aggressive gearing. If you haven't run this I think it will make the bike a bit of a PIA for general street and touring riding. I run a 17/45 which is -1/+2 over stock and it really keeps you in the thrust over stock but fuel usage and noise/vibration goes up. Anyway a 112 link 530 will fit on my setup so it will probably work for a 17/47. However I always buy a 120 just to be safe. If you cut the chain so that it is towards the front of the adjustment range you can get 1/2" out of the wheelbase, good for twisties.

17/46 will fit the stock length 112 link chain, and of course let you go back to 18/46 if the 17 is too much for your preference.
17/47 will be tight on a stock length chain, especially if you're heavy. I would add a couple links if you want the 47.
The 47 will be more hassle and really overkill. Keep it simple and stay 17 or 18 front and 46 rear with a stock length chain.

Yeah, I think I'll take the advice you fellas have given. If I make a gearing change at all, it will just be a 17t front and leave the rear at 46t. I'm hoping to go with the stock length chain. If I do remove the front sprocket, can I put a new chain on without opening the master link? Is that even possible?

remember to get a speedo healer im +2 in the rear and still get good fuel mileage on a good straight trip I can get 43mpg but most of the time im in the lower 30's

No - you can't remove a chain without removing the master (or cutting any link really) and chains come
with the master link unattached so you need to put it on - and yes you need a tool to do that.

18/43 is stock so going to 17/46 will be a BIG change especially if you are stock length swing-arm!

I can't see that being fun unless you are a BIG guy..

I'm 193lbs in full leathers, and 18/46 and 17/46 is ALOT of fun on a gen2.

Maybe fun was the wrong word,.....it would be fun if you want wheelie city but I can't imagine running any decide times on that setup SWB...

With the 17/46 gearing are you planning to drag race ? I am desperate to improve my time on the drag strip and am about 220 lbs. Would appreciate someone knowledgable advice on how to go about it?
