Hi All,

New to the forum, just had a question regarding rear sprockets for an SL350 K2... I want to find a smaller rear sprocket in order to lower the RPM at freeway speeds, with the stock gearing (16 front / 42 Rear) I'm hitting about 6500 RPM at freeway speeds, feels like the bike is about to rattle apart from underneath me. So my question is, does anyone know if there is a smaller sprocket from a similar Honda twin that will fit the SL350 K2? I would like to find one on ebay rather than buying new to save some cash, but don't know which ones might fit. I know most of the sprockets on Honda street bikes (CB,CL,etc) are fit for a 530 chain, while the SL350 sprockets are fit for a 520 chain, so not sure exactly what would fit. Also, any input on what size sprocket would be best? I'm thinking 36 or 38 teeth on the rear (from the stock 42) and leave the stock 16T on the front.

Thanks,
-Jay

520 and 530 chains are the same pitch (5/8" pin to pin) but the 520 is narrower..... it would probably be easier and cheaper to add teeth to the front sprocket (a 17 or 18)

Thanks for the reply, didn't realize that the 520 and 530 were the same pitch. I think I may look into getting a 17 tooth for the front after all, like you say, probably easier and cheaper. I think I might have found one on ebay that will work, about $30 with shipping, so not too bad. :)

Thanks!

Try Sprocket Specialists.....Should only cost about $15 for a countershaft sprocket (or am I living too much in the past)... :shock:

Checked out the sprocket specialist, only $22 there for the 17T front sprocket, so that's a little better.

Thanks for your help, much appreciated!

if you buy from sprocket specialists make sure you count your teeth.. I ordered a 36 tooth rear sprocket and received a sprocket stamped 36 teeth, but a count, and recount found it to be a 38 tooth sprocket! that and the groove for the drive pins was not centered on the mounting holes, had to file flats on the inside edge of the grove to accept the mounting bolts. minor nuisances it took a couple of weeks for delivery, It was a custom piece, ultralight aluminum....

In the future, for SOME parts, you can use the link that I've provided and find out just what all bikes that a certain part might fit. You simply go to the left side of the page, put in the proper info of the bike YOU have AND then, when you get to the page that has the P/N, copy the number, then back up to the 1st page again and put that info and the brand of the bike in there and search. DO NOT put the model info in there and it will tell you every model of THAT brand that the part was used on. Pretty cool feature. I used it and found out that the upper part of the triple tree on the SL350K2, is the same as some XL250 & XL350 Hondas as well. Found me a replacement that was fairly priced and in good shape. Worked for me. ;)
