Sprockets?

[Red_250EX_Rider]

How long will front and back last? How much top end will i lose if i go to a 14t front and stock back?

[hocman123]

how long the sprockets last depends on a lot of things if it is steel or aluim. and if u had proper maintenance by just loobing the chain often .but when they go bad u can tell by looking at them and seeing if the teeth have like a wave look to them. the wall on both sides should be even.

and this will help u pick i size

also get a new chain when switching the sprockets for longest life of all.

As long as they were steel sprockets, I would normally get twice the life out of a rear compared to the front. It's recommended that you change both sprockets and the chain at the same time, but I never had an issue replacing just the front sprocket once before replacing all three.

Also type of chain, quality of chain, and riding conditions have a lot to do with how long they last. So as you can see with all the good answers that it’s hard to say really how long it will last you. I generally replace mine every season but it sometimes varies, I don’t let it get completely worn out before I replace it.

steel lasts a VERY long time, aluminum not so much.

My stocker 15t front is still fine after years of abuse and riding. Up until recently I had all stock stuff and the quads 10 years old.

you will fall flat on your face on top with a 14t
