Making some progress – installed you can see the entire rear suspension (with rear hubs from a 250r) and front bumper from a 450r, longer A-arms from a 400ex, along with spindles, hubs, brakes, and shocks from an 300ex.
Once that was done, it was on to other details, such as
the battery box,
the engine (new piston/cylinder, ported head, 200x cam), shifter, footpegs, gas tank (200x), rewired electrical harness, etc. Just behind the drive sprocket you can see the fabricated tab for the ½” diameter, 13 inch long, Grade 8 swing arm pivot bolt. There is just enough room between the rear of the transmission case and the front of the swing arm to slip a .030” feeler gauge through. The battery box is mounted to the upper rear engine mount cross bolt, isolated by rubber grommets. It sits just above the front of the swing arm.
The controls - the bars, dash, left brake lever (now hooked up to the parking brake on the 450r rear caliper), throttle, and electrical switches are all original 200m parts after being cleaned up, repaired, straightened, sandblasted and painted. The right brake lever is a hydraulic master cylinder for the 300ex front disc brakes.
...and, it's finished. All the bodywork (front and rear fenders, hood, and seat) are from a 450r, trimmed just a little to fit and painted satin black. The gas tank is from a 200x, the muffler is from a 450r (turned 90 degress clockwise and mounted under the seat), the exhaust pipe is bits and pieces from several different trikes cut and fit, welded, painted with high heat paint and wrapped. The foot pedal by the right foot peg originally activated the rear cable acutated drum brake on the 200m, it's now modified to activate the hydaulic master cylinder for the 450r rear caliper.
