REAR SPROCKET 46T, UK LFH
46 tooth rear drive sprocket, UK LFH spec, part number 37-1499.
This is the 46 tooth rear sprocket, part number 37-1499 (also seen as 37-1499S), sitting at the back wheel where it takes the drive off the final drive chain and turns it into motion at the rear hub. The description in the catalog notes it as a UK LFH spec unit, which is the kind of detail worth having in hand if you're matching it against what's currently on the bike.

This sprocket pairs up in the final drive line with a front (engine) sprocket and a chain, and wear on any one of the three usually means it's time to look at all three, since a stretched chain will chew up new sprockets fast and an old sprocket will do the same to a new chain.
Our records on this one are thin beyond the basic description, so if you're not sure this 46 tooth sprocket is the right one for what's currently on your bike, give us a call and we'll help confirm before you order.
