125-200cc 12 tooth counter sprocket

Want to gear down a CR 125 for the Las Vegas Endurocross on Nov 20th Already run a 52 on the rear and really do not want to go any bigger on the rear .So any one ever use a 12 tooth on the front

Ajax,

I have been running one all year. I thought it would wear faster than the 13 but seems about the same.

Check with kelly, he runs both 12 & 13 and has them on the shelf.

I've got a 12 on my TXC 250 but still run a 50 on the rear. I've been told one tooth on the front equals 2 or 3 on the rear so I'd be afraid of running a 12/52 unless you really want to tractor.

all we want is a tractor for the endurocross Then it is back to desert racing where 13 52 works great

been running 12 / 50 for a year now... works great ! now that I'm getting the 167 on may go to the 13/50

id rather run the 12/50 combo,you risk banging sprocket off rocks and tossing the chain with the 52t rear

You should definitely tractor right along with a 12/52!

John,

I run a 12x49 combination with the 144 and it works well. 12x52 will probably be ideal for enduroX. What are the dates for the Las Vegas EX?

Endurocross - youre a brave man - Good luck
