I've already stated elsewhere on here that I'd buy another DR650 at the drop of a hat.
The CRF250 Rally , absolutely . For the money it's bloody amazing and costs sixpence to run.
The Van Van, no I wouldn't buy another one, it's just a fun thing for sunny days.
Now the difficult one, the Tenere 700. I love that bike, the engine is so smooth and so willing, it looks good and has great road manners but I'm not sure if I'll ever buy a bike that big again.
