1200 bandit mk1 front sprocket

[Alex]

Hello all. Would a 17t front sprocket fit on the b12 without hitting the clutch push rod? Thanks in advance alex.

15T is the biggest you can go without modification, 16T you need to remove some of the meat from the rear part of the cover where the fixing bolt gose through.

Never tryed a 17T.

@wraith Is this for 530 or 630?

Wouldn't it be easier to change the rear sprocket?

Confused ! The Blandit bottom cases are pretty much the same as a GSXR - Yes?

I've fitted 532 pitch, 17T sprockets to both my Turbo'd GSXR engines without any problems - both were 3/8" / 10mm offset for chain run. Admittedly the clearances were minimal but they worked fine!

Losing 6 or 7 teeth off the back means you get into chain run problems over the S/Arm pivot. Besides, a 17T front is kinder to a chain than a 15T. 18T would even better but that eats through everything LOL!

I have a triumph t595 swing arm I need the clearance on the swing arm. A 15t rubs the chain guide to much. I need to go as big as I can on the front as a triumph has a 18 or 19. Also I am running a 247 whp turbo engine

I forgot about the rocker arm. You're right.
Two more teeth in the front is actually six less in the rear.
As for the sprocket cover - I have a 1052 cover in 1157.
This critical bolt is not compatible with the crankcase.

Yes it does fit I needed to modify the cover by omitting bolt 26 and trimming the spigot that it goes through.

Pics to help 

 

17t front hits the rear bolt that holds sprocket cover

16t misses bolt just

But u less you have one of these gsxr covers you need to remove some meat from cover

17t as you can see chain just misses clutch push rod

All the sprockets above are 530

And before some dimwit start's saying 525 or 520 sprockets are smaller top sprocket is a 520 bottom one is a 530

If Gixer1460 had put a 17t or more on his bike without altering anything he has got some sort of special powers we don't know about, or he is using the 750 gear box with the clutch on the clutch cover.

Pictures don't make mistakes

I run 16/43 on my Turbo GSXR with 260hp on its best dyno readout. It's the happy medium for my set up, hit 200mph on the dyno as well not seen that on the road though. As Wraith says I had to remove some material from the case on the back bolt.

I obviously subconsciously removed the offending bolt / casting - no superhuman powers! Its not as if there are only two screws holding the cover on - don't stress, you can lose a couple!

What about number 26?

Sorry Alex I have just double checked my sprocket cover. My mistake bolt 26 is one to omit and to trim up the spigot off the casing. Sorry about the error I have edited my reply

thanks all for your help today, much appreciated.
