Buying an SP-1? Keep it original

The SP-1 is built with real precision and a very high level of finish, however there are a few things to look out for when buying a used one. The first is originality as they are viewed as collector’s items so you want the original exhausts, licence plate holder, screen etc. The SP-1’s wiring loom has an exposed area under the seat, which can rot through next to the bank angle sensor. Any damage can cause the bike to misfire and even cut out, so check for any signs of corrosion. Both the SP-1 and SP-2 suffer from a weird issue where the screen can act like a lens (it is worse with aftermarket double-bubble screens), focusing light on the top of the dash and melting it, so check this area for damage. Finally, always scrutinise the bike’s service history. The SP models have 4000-mile service intervals, however at 16,000-miles the valve clearances need checking, which is a bill of around £600 as it is a complex operation requiring precision and accuracy when it comes to HRC’s specified tolerances!

Joey specials

In 2002, British tuner Russell Savory created a limited run of SP-1 models to celebrate the life of Joey Dunlop. With a paint scheme based on the bike on which Joey won the 2000 Formula One TT the bikes had the backing of Joey’s widow Linda. Only 26 were built, one to signify each of Joey’s TT wins, with each one having a plaque on the billet top yoke with its individual number and Joey’s signature, OZ Racing wheels, carbon hugger, Laser exhaust, Power Commander and a WP shock. The bikes cost £14,300 and now change hands for anything upwards of £17,000.
