XT600E - Larger Rear Sprocket

**mbishop** · #1 22 Dec 2003

Hi

Having fitted an 18" rim and put a 14tooth front sprocket on my XT600E, I still want lower gearing (the bike spends most of it's time trailriding) - I can only source a 47 tooth rear sprocket but ideally require something in the 48->50 range...

Can anybody point me in the direction of a supplier.

Thanks
Bish

Try B&C Express on 01522-791369 or www.bandcexpress.co.uk.

There are also other suppliers in the Bikemart section of MCN.

Thanks Steve, but I've drawn a blank so far.

Renthal don't list anything other than standard for the back. Evidently if I went for an alloy, rather than steel, one, it wouldn't be a problem - other than the fact it would wear out in seconds!

If anyone else actually runs a large rear (steel) sprocket, perhaps they could advise where it was sourced from.

Aluminium sprockets do not "wear out in seconds" if lubed & the chain tensioned correctly. Admittedly, they do not last as long as a steel item & cost more but it's either that or permanently having the wrong gearing.

I used to run one on my old GSX-R as I'd fitted an OW01 rear wheel. It gave good service for 5,000 miles. I only replaced it when I fitted a new chain.

Why not try the standard 47t rear sprocket with a 13t front? This would give a ratio of 3.615:1. A new 13t front (from B&C or similar) should also cost less than the aluminium rear?

14/47 = 3.357:1
14/48 = 3.429:1
14/50 = 3.57:1

I would never try a front sprocket with less than 13t on it (unless it was a very small pitch chain?) as it's possible that this leads to too tight a radius for the chain to turn effectively?

Hi Bish,

The Renthal site shows the range available:
http://www.renthal.com/site/products/cwmakes/yamaha.asp
I would give them a call direct, or another of their distributors (see site). Failing that, I would go through M&P in Swansea.

The Renthal site also has a Technical section with the gearing ratios.

Good luck, Geoff

Steve & Geoff

Thanks for your replies - I will try B&C direct, as the renthal.com site does show more choices than I'd been advised...

Cheers
