This morning, just after 10am, my parts arrived! They also sent a 272-page full colour catalogue for spares and accessories for the Royal Enfield Bullet range (they are Royal Enfield specialists after all!), which also contains many items which could be useful for other bikes, ie. handlebars, levers, grips, wheel rims, spokes, etc etc.
Hitchcocks seem very business-like and I reckon I shall be using them again. Why not check them out yourselves? They have a website @ http://www.hitchcocksmotorcycles.com/ and their email address is firstname.lastname@example.org
