A bit off topic. I have a picture from the paddock in Isle of Man 2007, the Centenary TT. It's a 250 V-four. As far as I know the factory destroyed all the old racing machines and this one is a replica I believe. The model is called RD05A and that model was raced in the middle 60s. Well I know that this is a Yamaha but still it's 250 four!
