Abstract: The invention provides a constant mesh reverse gear operable by a standard rotary shift drum and fork system which is located within the engine casing along with from 3-5 forward gears of the motorcycle transmission. The reverse gear is mounted on the countershaft and engages an idler mounted on its own separate shaft in engagement with a main shaft reverse gear. The idler pin is secured between a pair of plates mounted on the transmission endplate. These plates also have apertures therein to receive the main shaft and countershaft. A standard toe-operated shift lever engages a shift arm which in turn engages a pawl and cam plate assembly for rotating the rotary shift drum. The shift forks are operated by pins riding in cam grooves on the rotary shift drum. An indicator plate on the cam plate assembly contains a contact boss. The contact boss engages electrical contacts in the rear of the engine casing so that the engagement of the transmission in reverse gear may be positively indicated.

Abstract: The invention provides an improved, independent swing-arm type suspension for three-wheel vehicles and includes a special yoke frame in which the rear axle is rigidly mounted, and cross rails for mounting a storage box thereon. The box is mounted directly onto the frame cross rails. The entire rear assembly is mounted by swing-arm pivot and triple spring/shocks between the main frame and the rear swing-arm frame assembly. This assembly moves the point of travel to below the rider's seat, thus giving improved ride and handling characteristics. The rear axle employs a fully engineered off-center differential connected to an in-line drive shaft for better performance and easier maintenance.
