Have been keeping a close eye on what is going on with regards to the 600,s.
Only Yamaha have made a new model to meet Euro 4 regs,
All the others have not imported any new bikes into the UK as far as iam aware to meet this spec,

The biggest problem, that I can see,
Is what is going to happen to the sidecars at the TT,
With no new engines about ?
There's only so long you can push these to the limit at the speeds they are doing,

And what would replace them ????

36 sidecars only this year,

Which is not looking good for them, Which would be a great loss to the TT !
