stark varg ex supermotard

On the MX KTM sprockets fit. So you have the range of 12-15.

I dislike the Stark ones, they are aluminium with holes drilled tru. They wear very fast and i know some people who actually were able to break them in 2 on hard landings with open throttle, in 1 case bending the drivertrain axle by locking up the chain.

I always buy aftermarket steel ones. Longer lasting, not breaking and cheaper.

I never buy aftermarket front sprockets because I fear that they may damage the countershaft because of some characteristic of the splines. For example, the splines may be too hard or have an excessive shape error or the wrong play.

Does that really matter on the lifespan of an MX bike though?

Also this is not a circlip mount, but a solid bolt connection. I never seen damaged axle splines on a bolt mounted sprocket. I have seen it with circlip sprockets with both OEM and aftermarket. I think it's more a design feature than a actuall sprocket issue.

Now that I think about it, I've seen it on circlip mounts as well; probably you are right.

honestly it doesnt makes sense to me to have a 12/49 gear... it will be uncontrolable, go and buy some wings my friend jajaja!

Just for giggles, I hit 80.8 mph while riding back from my training course today (per the stats on my Varg phone) with the 12/49 combo. It was all dirt, pretty straight and not too whooped out. Just a twist of the throttle for only a few seconds. I'm sure there was more to be had.

Hey guys I’m running into an issue where the rotor is hitting the brake caliper or something inside in between the pads where it spins backwards but you here the clicking from the brake rotors rotation. It won’t spin forwards because the click basically locks it from spinning any more fwd. I do have the brake caliper extension on. Seems the rotor they put on is massive. I swap it for the ones that came from factory on and it spins no problems but no longer have a front brake.. do I get rid of the extension and it’ll fit snug? Made sense to have it on being the new rotor is massive. Couldn’t find a single video of someone doing a compete install from start to finish. Using just the rear brake for a test ride. Holy fuck this thing put a smile on face in the first five seconds

See if the bolts that attach the bracket are too long. If so either shorten them or use shorter bolts.
