WHAT TO LOOK FOR
1 RACE KIT Power will go up from 102105bhp to 136 or so at the wheel with the race kit fitted. Race kit headers mean the stock rad and fairing won’t fit. A race-kitted engine retains only the stock crankcases, crank, conrods, and clutch.
2 R vs S Frames on the two models have different part numbers and the later bike apparently had its engine moved forward by 7mm. However Steve A’lee has been unable to compare the two to confirm this. Airbox lid and rear rocker cover changed but these parts are interchangeable anyway.
3 GEARBOX See ‘Engine’ below. The GT Motorcycles race bike hasn’t even had a new clutch.
4 ENGINE You won’t break it, you just won’t. GT Motorcycles’ endurance race bike has done over 100,000 racing miles without issue. As an experiment the team hasn’t changed the oil for two seasons with no problems.
5 FUEL PUMP Denso fuel pump is one of few areas where problems have been experienced, mainly through standing with old fuel in them. Manky old unleaded takes a toll on fuel filters too.
6 FUEL INJECTION Lack of use is again the main cause of issues here and the dreaded old unleaded. You’ll need to spend £100 or so to get the injectors clean on a bike that has stood.
7 SUSPENSION Standard road bike fare is Showa, so spares are easily come by. There were some Showa race kit forks too. Öhlins did a shock and linkage, a desirable extra.
8 16-inch FRONT WHEEL Many owners opted to fit VFR and aftermarket wheels so they had the option of a 17-inch front. However originality is now very much the order of the day and stock wheels attract a premium.
9 SERVICING Given how few miles most RC45S do, servicing is often neglected. Ask the vendor what his service schedule and practice look like.
