I´ve tried getting parts etc. for my bike and it´s a right nightmare. No shops know any aftermarket parts that fit etc. The best thing to do if you need new parts (including Engine) is to Phone the importers. Their number is 02086659994, It´s a croydon number. They´ll get you the parts but don´t expect them to be cheap. They wanted £60 for front and rear sprocket without a chain. Bearing in mind Talon can knock you up copies in solid alloy for around £80 you´ll be getting you´re **** ripped out but it´s always a last resort.
