Ron Major's Speed Sensor Bracket

Below is a photo of the front wheel of Becci's 1994 Honda ST1100 ABS. Of interest here, other than the beautiful black color of her ST, is the Ron Major speed sensor pickup mount on the front axle. This mount is one of only two that Ron made before his untimely death while competing in the 1997 Iron Butt Rally. The other one was on his rally bike. The mount was originally designed by Ron to hold the Hall Effect sensor for his Alpha Rally computer, but adapts very nicely to a magnetically actuated reed relay. These relays are very inexpensive and easy to find, but they are also very fragile. Most installers, therefore, mount them at the rear wheel location to protect it from road hazards. The ideal location, however, as all pro rallyists know, is the un-driven wheel (front wheel on the ST1100). Ron knew this also of course, so he engineered this bracket for the front wheel of the ST1100. Needless to say, in Ron's usual way, it was designed to work unfailingly.

The next photo below is a close up shot of the front right fork leg and axle to show more detail of Ron's speed sensor bracket. Note the location of the potted reed relay (red and black leads coming out to rear) and the round disk magnet epoxyed to the wheel hub. This setup has been on this bike for over 50,000 miles without a single failure of either pickup sensor or Major Sensor Bracket. Other methods I have tried on ST1100's have failed in as little as 15,000 miles of hard rally abuse. Click on the photo for an enlarged view.
