fitting BMW K100 bars on 2000 st1100 ABS
Just finished fitting a set of BMW K100 bars to my st1100 (2000) ABS. I read various threads before I started, which gave me a head start, and heres how it went. Got the set of bars from e bay (cost me ?20). After removing the plastic surround that covers the bars/ignition switch, i could position the BMW bars next to the originals and get an idea of what needed doing. The first thing that was apparent was that the hose from the master cyclinder to the ABS modulator wasn't going to be long enough. Everything else looked like it could be rerouted and would be long enough. Removed the switch gear from each bar end and the brake and clutch master cylinders and twist grip, and removed the handlebars. Getting the rods that the bar end weights screw into out was a problem, ended up cutting the bars and knocking the rods out. The BMW bars have a slightly smaller inside diameter, so getting the rods and their rubber grommets into the new bars was a bit tight, but a large hammer solved the problem
After loosely fitting the bars to the clamps, I could start moving/re-routing the various cables, wires and hoses to behind the triple tree. This went without a hitch, the only problem was the brake hose. I got the necessary parts from
http://www.venhill.co.uk/ to make up a hose 150mm longer than the original item and this turned out to be spot on for length when fitted. Some posts say that the plastic bar/ignition switch cover won't work with the BMW bars but with just a small trim to each side, the cover fits quite well (although I think it looks better without the cover and i'll probably leave it off). All that was left was to bleed the brakes and give the bike a test run. As i'd hoped the bars give me an upright seating position and I find the bike much more comfortable, the original bars made me lean forward a bit more than I liked so i'm well pleased with BMW bars. Having got the riding position sorted the next step is a new screen!
