A lot of Triumph Rocket owners have realised that their bike is restricted. So that’s usually the first question we get when they come in! We can remove the restriction in the secondary butterflies – which is variable by gear – but can’t take out the top gear restriction that knocks 1,500rpm off the top-end.
To be fair, that’s not such a problem on this model because at warp factor 5 hanging onto it maybe an issue… Once remapped, de-restricted and fuelled correctly these things make great torque. And lots of it! The service was straightforward – oil and filter and a thorough check and go-round the entire bike.
