Additional FeaturesThe Trimuter was designed by Robert Q Riley of Scottsdale AZ and first appeared for home building in the February 1980 issue of Mechanix Illustrated.

This Trimuter was originally built by James A Beck back in 1982/83. I purchased it in March 2004. I spent from 2005 to 2008 doing a complete tear down and rebuild, this included every part, nut and bolt being taken off and re-furbished or replaced.

The body is hand-laid fiberglass over foam board. The fiberglass work is excellent with every line straight as an arrow. In my opinion this is the best Trimuter I have every seen on the net or E-bay. The workmanship is top notch and of excellent quality.

New Alltrax 7245E 450 amp motor controller
New Zivan N1 72 volt 12 amp charger
New dual master cylinder from a Suzuki Swift
