‘A set of aftermarket pipes makes them sound awesome!’
“The SP-1? Now that’s a nice bike, a wonderful bit of kit and the only thing I’d really say is crucial when buying one is a good service history. They need regular oil changes to keep them in tiptop condition and I’d avoid any with too many race parts on them, especially within the motor. Stock is always best, although a nice set of aftermarket pipes makes them sound awesome!
“One of the very few known faults with the SP-1 is the wiring loom. If they are used in all weathers I’ve seen them start to corrode their wires below the seat, mainly next to the bank- angle sensor, which can rot its connector. This can cause the bike to cut out, but generally they are a very solid machine.
“The level of finish is incredibly high, the paint is lovely and thick and the fasteners are also well plated, and when you get the bike’s panels off you can really see the quality. The motor has no cam chain tensioners, it has gear- driven cams, so that’s another worry gone and the valve clearances seldom need checking. Honda recommend you check the valve clearances every 16,000 miles, with services every 4000 miles, and I love that the valve clearances are measured precisely – there is no plus or minus, it’s a set value. That’s so HRC!
“Occasionally the exhaust gasket on the rear cylinder can start to blow, so give this a check, and watch out for track bikes as the only time the V-twin can get unreliable is when it’s been thrashed on track. Hammered track bikes with quickshifters fitted can wear their gearbox dogs and as there is no slipper clutch they can also be overrevved, causing valve damage. Some owners complain about the clutch being snatchy, but I don’t think it is bad at all, and the same goes for the fuelling – it’s abrupt. That said, I’ve seen loads of riders stall them as you need to work the clutch when pulling away. If your bike has race cans I’d recommend a Power Commander.
“Just watch out for double bubble screens, they can focus the sun’s light and melt the top of the clocks! Honda supplied a small dash top cover with their larger screen to stop this happening.”

Get the stock cans thrown in and check the dash hasn’t been melted
