Fits great.
Won't fit a 74 XL250 without mods.
By David K. on
Verified Purchaser
This will not fit a 1974 Honda XL250. It fits the output shaft, but the chain will not fit down on the sprocket. The chain hits the engine case. The case would have to be ground away all the way to the output seal. Probably not a good idea. Maybe a spacer between the housing and the sprocket, and use an E-Ring retainer on the shaft instead of the stock retainer and bolts. Haven't tried that yet. Going to order a 14 tooth and a 50 or 51 rear sprocket to get close to the ratio I want.

Questions & Answers
Do you have with 14 Teeth?
By John
OEM for 2007 Honda CRF 250 X is 14T,
Not 12 T. Correct me if I'm wrong. Thank you, John.
Once you select the 2007 Honda CRF250X 4-Stroke from our fit guide, you'll be given the choice of 12T, 13T and 14T sprockets for that machine. As you've noted, yes, that particular bike came from the factory with a 14 tooth countershaft sprocket. Just choose the 14T unit from our fit guide and you'll be all set.
Will this sprocket fit a 2005 polaris250?
By Anon.
Yes, so long as you select the correct year/make/model before adding to your cart, you would receive the correct sprocket to fit that machine.
