You have seen that we are introducing drive shafts with 2.0mm pins. These are new parts, not changes to the existing parts. These new drive shafts have been developed for the DEX410R model as we feel that the users of this slightly lower end model would not have so much experience with setting up of the slipper clutch, making the use of slightly stronger pins necessary.
