Sinroja Motorcycles R1

The design philosophy behind this build was to create a clean, simple and rideable motorbike. One of their USP is Quality and to make sure the bike was perfect, the bike got a full ground up, nut and bolt rebuild. Sinroja Motorcycles changed everything from each and every screw, nut and bolt to stainless steel to doing a full Zero Hour rebuild on engine, gearbox, clutch and drive. The whole electrical system was re-configured, with new looms and a Motogadget keyless ignition system. To finish it off, the whole bike got new Hagen rear shock and front progressive springs customised for the bikes requirement. Billet aluminium indicators, new headlight, Renthal low bars and Motogadget Motoscope Speedo were just the icing on the cake.
