Hitchcocks are really good. Great service, fast delivery. I try to use them if I can. Thing is, the prices are approx double or more what identical parts are from India inc postage. So if you are not in a hurry (I'm not) then EBay works well.
As an example: A front disk upgrade kit (disk+caliper+complete new front wheel+master cylinder/lever+fitting kit) is £495.60 plus postage from Hitchcocks. Whereas from India £143.91 delivered. Identical factory item.
Sometimes you might have to pay duty but often not. Even then it's a massive difference. Delivery times are long as they are often sent by ship.
