Little help needed, what year model LT bars can I use? I have an 85 K100RS, I assume I need clutch cable from LT bike and throttle cable and dash pad from LT bike??? Thanks for the help!!

A new throttle cable, clutch cable, 'choke' cable and dashpad are needed, plus the extended hydraulic brake hose to fit the LT or RT 'bars. A local source can perhaps make you one if the BMW dealer isn't an option, otherwise there's Spiegler USA in Ohio.

Any 22mm diametre 'bars will work from an RT, LT or even the R80RT/R100RT 'bars, though the bar end weights and any wires for the heated grips (if fitted) will have to be dealt with appropriately. It's best not to attempt to use standard 7/8" 'bars unless you relish scraping off that .225mm of chrome or paint to get them down (and perfectly round) to the size you need to be able to slide the switches/controls on easily.
