    You gain an extra plate set, and reportedly a no mod bolt in.

    The problems are starting here.



    The TTR does have a other toothing as like the TW.

    If you want the 6 disk clutch, you have to install the TTR shaft.



    But the TTR shaft does have a 6 speed transmission.

    You will need a 6 speed output shaft.



    The next problem, the 6 speed transmission does have a shorter output shaft as the TW.





    The summary

    What you need:

    - inner and outer clutch basket from a 6 disk clutch

    - 6 speed transmission

    - and you have to find a way to enlarge the outputshaft

    Add some washers if you want better hook up.

    You can also install stiffer springs.



    The following is one of my company secrets.

    I can tell you this, because I can not make good deals with you:

    -> shipping is expensive

    -> USD-EUR exchange rate is bad for you

    These reasons will make for you standard parts a bit expensive.



    The clutch springs from EBC are 10% stiffer, as the OEM springs.

    The fitting springs for the TW does have the number CSK052.

    -> This is not the secret



    But I've found a other set of fitting springs.

    CSK002

    These springs will fit perfect on the 2001 and newer models, because Yamaha has changed the pressure plate a little bit.

    All other bikes will need a small modification. There must be removed a bit material from the pressure plate, because the spring diameter is a bit bigger (~0.8mm bigger, but you don't have to remove so much -> ~0.4mm).

    Sorry, I not describe it better. I hope, you understand what I try to say.



    I've made a small calculation to get the spring rate from the different clutch springs.

    -> I don't know the exact value of "G = modulus of rigidity", but I use 81.500 N/mm² as basic value for the calculation.

    13,40 N/mm² -> OEM spring

    14,74 N/mm² -> CSK052 -> 10% stiffer as OEM

    15,69 N/mm² -> CSK002 -> 17,1% stiffer as OEM



    I've ordered some other springs from EBC and I want to check these springs too.

    Trust me, sometimes I have the same wish.

    There are much more TW diver in the US as in the whole European Union.

    -> I don't know it, but I am absolute sure about this fact.
