Rear Sprocket crossover

[lankydoug]

Is it true that a Husky rear sprocket is the same as Gas Gas. If so what years are compatible?

 

[eff]

Almost all late model. That Husky WR250 should have the same rear sproket. The JT rear is JTR822

I put a gasgas rear 52t on my 2010 husky 250F direct bolt on,pretty sure like eff said,they are all the same from 98? on up

 

[lankydoug]

Great! I'm going to put a 51 or 52 Ironman on my 200 along with a Pirelli MT 43 with a tubliss set up plus a new chain and turn it into a tractor. At least that is my brilliant idea of the week.

Been using Husky rear sprockets for years. Late model years bolt right up. Iron Man, AFAM no problem. I run a 51 tooth on my rear of my 200.

Good Luck

Does anyone knows if KTM's rear sprocket is compatible ?

 

[GMP]

No, but a KTM rear rotor is. Rotor bolt holes and OD the same with a mm or so larger ID but makes no difference. I have used them.

A trials tire has a much larger outside diameter which makes your overall gearing higher so you might want to go with the larger sprocket to compensate. Also trials tires are enough bigger that they can eat up your rear shock protector flap unless you make the chain 2 links longer.

A 91-93 Suzuki DR250S also uses the same rear sprocket but it must be the "s" model, the DR250 is different.

+1 I found that out myself when i went to trials tire with stock rear, I wondered where all my low power went to until I did the math. In my case my old S-12 @ 130/80/18 was 81" in circumference and the X-11 Trials @ 4.00x18 was 83" in circumference. Not a lot but did make a noticeable difference. (& mine is a 250). I run 13/51 gearing now & at times think I could stand a 52 or 53 even

That's good to know Fred, I think I'll go with a 52 or 53 since my 200 won't have as much down low as your 250. It's those leaf covered marbles at Mary's place that's forcing me to do this. See what you got me into.

What model and year please Inquiring minds need to know.

 

[GMP]

'99 EXC rear rotor I'm sure of, so whatever years retain the same rotor pattern/size, which I suspect are most late models.

Moose lists KTMs to '06 and Husabergs through '10 as having the same rear rotor as the Gassers.
