I know you can't justify what exact length of chain you need with out having the stuff on the bike but by estimation would a 150 link be long enough for a 63 rear and a 14 front? I'm thinking no...but HAI's site says a 150 will generaly fit +20.......it would really help if anyone had a constructive responds....thank you!!!

what was the stock chain length, and what was the stock gearing?

Two teeth take up one full link if I'm not mistaken........

im runnin stock front sprocket and 66 tooth rear on my f4i and a 120 link fit hell only thing you'll ever need anything bigger than a 120 is if your extended

also it depends on the bike.

Some bikes use 112 links stock, so if they go more than 16 up on a stock front sprocket, a 120 wont fit.

My buddy put a +15 on his 1000rr (don't ask why b/cause I don't even know) and it took a longer chain.

I had -1 +2 and then I went with a 67 tooth on my R6 and I think I only needed 6 more links on my chain. I would say that a 120 would fit but a 150 will Def. fit on that setup.

Here's a link to a chain calculator. You'll need to know the center to center measurement between sprockets. You can find several calculators if you do a search or if you're ambitious, you can find the formula for how to do the math yourself. I prefer the calculator:YEAH

When I ordered my 62tooth sprocket from sprocket specialties, i used the calculator and it was helpful then doing the math my hand.
So if your lazy or want reassurance then use the calculator.
