crs-and-rms,
The plastics were purchased as if they were being fitted to an RM465 as this was the closest model possible to the PE175. I had to;
1. Add washers to the rear bolts to angle the front mudguard away from the exhaust as there was an interference.
2. Make a brace to hold the front plate, a $45 genuine Suzuki part, as the distance between the tripple clamps on the RM & PE are different. Again this was a simple task.
3. Make mounts for the side covers as they did not fit, obviously because they were for an RM. Given that the frame profile was almost the same as the PE, they ended up fitting like they were meant to be there. I also had to make a mount on the rear muffler to hold the left hand rear mount of the sidecover.
4. Fabricate a rear guard mounts (replicated from an RM) and that also fitted up like it was meant to be there.
In the end the fit and finish were as good as what the factory would have supplied, except that you have to drill the locating holes.
In the case of the rear suspension, most of the parts are avaliable ex Suzuki, only problem is that you have to mortgage your house to get them. What i did was use an All-Balls kit (P/No-28-1137) for the swing arm bearings. I bought the spherical bearings for the rocker from a bearing supplier in Dandenong, mind you they were $45 each, and the rest of the bearings in the bike were serviceable, however i did replace all the "O" ring seals in the link rods.
The seat was done by Mario from TopLine Upholstery and included a new foam (to my spec) and a new cover with the stencil. Mario does hundereds (literally) of bike seats and knows his stuff backwards.
