The are made in Holland out of the best quality stainless steel and much more strong then the "Taiwan models".
They fit also older engines equiped with the OEM CV-carburator if they are combinated with the adaptorkits PRO-11236 (for Shovelhead 1978-1984) or PRO-11238 (for Evolution 1984-1992). With adaptor kit PRO-11240 these brackets also fit the Twincam models.

Our Pro Street front motormount kits are available as an off-set kit for Pro Street frames and FXR and FLT models as well. The off-set kit must be used in combination with our extra wide swingarm. This combination allows the use of up to 190 wide tires in the Pro Street frame. It's also possible to mount this combination in a OEM FXR or FLT frame and allows the use of up to 170 wide rear tire. If you cut the rear frame rails (for the rearfender mounting) you can even go to 190 wide tires in a OEM frame.

This reinforced spacer is the solution for the weak spacer behind the Big Twin transmission belt-pulley from before 1994.

SIMPLY-THE-BEST STARTING SYSTEM
The old starting system with seperate starter solenoids is far from "bullet-proof". On the 4-speed electric start models from 1965-1988 is a good working startsystem more luck than good development. Our made-in-Holland starting system is real great thru his simplycy. No more destroyed push buttons and solenoids. Remove them al and replaced them with this simply-the-best starting system. In the future you step on your bike, give the handle a push and ride away with a smile. It's possible to use an original starterrelay, however we advise to use the Pro Street starterrelay because the more simple mounting and stronger construction. This Pro Street relay (parnumber PRO-11302) is also much smaller then the original.
This starter system fits the following models: FLH 1965-1984, FXE 1971-1984, FXWG 4-speed 1985-1986, FXWG 1980-1988.
