Don't go for WP, had loads of problems fitting them 3 months back and forth to the factory - Customer service was S*** (I had to pay postage both ways)
It then only took 15 - 20K before the springs started to rust the vinyl covers just feel off!!! They told me Tuff - Top Customer service again
That said they are still on and have worked well now done 50k + just look very second hand..(Not that the rest of the bike is shinny any more)
