    I'm posting on a internet forum with general thoughts and information not to you specifically. (did not quote you) All the new huskys (KTMs) use them it the clutch pack too as does the clutch in the 449/511 (no coil springs)

    My understanding is this does not slip unless under a large load like landing from a jump in a low gear with the throttle off type situations. More of a fail safe than a constantly working item. Might be wrong but think thats the intent. As such it should not see continuous wear unless it is slipping abnormally.

    Not sure if the counter rotating engine, clutch on the crank and other unique features prompted this design. I assume they did as it was designed in there from the start. Only the original engineers know I guess. Tinken said 3rd gear is amazingly small when he swapped out his trans for the BMW 5 speed.

    I don't expect the rotation of the engine would change anything torque wise, just the requirement for 1 more gear in the train to get the sprocket shaft to go the right way. Gear or TL gear-set, either would work.
    But yes, looking at those gears, they are small.
    Perhaps it was done to reduce the wieght of the gears themselves & the limiter intended to save them from harm.
    As you've said, only the engineers would know for sure.

    A metal toothed 'Detroit locker' style spring loaded tooth set calibrated to release at a certain pressure would likely work, but it would take some machine work & a whole lot of developement for something that really isn't that dear or difficult to replace....

    Could the current gears be heat treated or would it make them too brittle?

    TL failure at around 160hrs/5000km enduro/trail riding. Tested at 114nm bike would still loft the front but had become 'untrustworthy' in this regard and occasionally slipped under very hard acceleration if grip was good.

    I have posted a positive oil feed mod on the ZipTy TL thread.

    Anything lower than 150nm, we replaced the TLs.

    Tinken, any means of getting a TL of you for a 2011 TE511?

    Berries, ZipTy does not stock TL. Your best bet is to source one through Bike Bandit as you posted in the other thread.
