Aye Ian,
I'm looking for something to pack up the rear of the tank by about 15-20mm - ideally some sort of rigid hard polyurethane or similar that I can carve up. Anybody know where I can get some?
Screwfix.
Screwfix_memory-foam-support-kneeling-mat-blackThis foam is ideal for any closed foam padding support that you desire. Glued with Evo-Stick. Can then be carved with either a hot wire, junior hacksaw blade, or similar. Sanded with 'production paper', choose your own grit.
I use it on top of a steel 'U' section, welded to the frame top tube to pad the fuel tank on the Ducati. I also glued three mats together, to form the seat foam on the Ducati, that was then covered with a peice if thin chip foam and finally, with some finishing foam to take the sharp edges off the seat outline once covered. At first it feels like a plank, but it is far more supportive than the squishy chip foam used on many seat remodelling/recovering jobs. The edges of the seat pan no longer cut into the back of my thighs and is far more comfortable than either the SRX mono or Honda Bros seats after a 100 mile jaunt.
There is also a similar product available from Toolstation, but this is of inferior size, when compared with the Screwfix offering and only a £1 difference in the price.
Toolstation_kneeling-matHappy carving and the health to give this beastie a canter.
