Yes it did. It is simple bolt on modification and it get cheaper than 1000€ (you can do it for 800€) You can use Yamaha WR complete front end. You just fit harder springs in it. My friend did it.

There is a few more upgrades like this.
Cheapest way is to buy WR with broken engine, take off what is good and sell the rest.

Another one here, but need to be registered.
