These rockets have the common Triumph cruiser problem of inadequate pillion seat and poorly shaped rider seat. The angle of the original Triumph sissy bar is not correct for the pillion rider.
This Triumph Rocket motorbike seat was custom shaped for the rider and pillion, including re-angling and re-shaping the back rest. Pillion seat was made wider and shaped to the bum, back rest was made thicker at the top to correct the angle and front seat was shaped to relieve pressure on the tail bone. The front seat had the gel removed before reshaping.
This was carried out by the owners coming round to have a fit up session, in which the motorcycle seats and back rest were all fine tuned and adjustments made before the final custom covers were made and fitted.
