Re: K7 1000 +3 rear sprocket question
I recently purchased new sprockets & chain for my K7 GSXR1000. Upon installing the rear sprocket I realised I had been sent out a 46T, not the standard 43T sprocket which I requested. After the initial 'face palm' and grumbling, I was about to mail back the rear sprocket, but thought to see what the forums said about it. This was the only thread I could find on a 17T/46T combo but wasn't very convinced after reading that I should keep it. I called a Suzuki Race Team workshop and asked their opinion. They happily explained for 20min the in's and out's of the 46T. They simplified it by explaining the sprocket ratio chart which settled it for me to keep it.
Standard Ratio of 17T / 43T is 2.53
-1 Front Sprocket (16T / 43T) ratio is 2.69
Standard 17T and the 46T rear ratio is 2.71
Obviously there is virtually no noticeable difference between the 16T/43T and 17T/46T (.02) and seeing I already had a new chain to put on, there wasn't an issue with fitment.
It also means at our local track at Phillip Island (Australia's GP track) I'll actually be able to use 6th gear now : )
