Mitch was also kind enough to send me his Parts Microfiche for the 1985/86 TG50 Gyro S or RoadFox. The original idea was to see if there were any parts that were common to other Honda scooters. Once a match had been found we were hoping to be able to list what performance parts from other scooters would fit on the Gyro. Unfortunately, while the parts such as cylinders and carburetors bear a strong family resemblance, the parts numbers show they are uniquely designed for the Gyro. The narrative below, however, shows that there are possibilties for increasing performance somewhat.

The following is an excerpt from an auction on eBay for a 1984 Gyro and seemed like a handy bit of info for any Gyro owners. I'd credit the author but don't know their name. If this was your gyro drop me a line so I can give you credit.

All oil seals and gaskets were replaced. The engine crankshaft is in perfect condition and both crank seals are new. The top-end of the engine has been reconditioned. The cylinder has been professionally stone-honed and dimensionally
inspected. The piston, piston rings, piston pin, pin clips and small-end rod bearing are new. I worked as a Honda cycle mechanic back in the 80’s and learned this: All 1984 Honda scooter engines came with low-compression, dished pistons. The low compression was supposed to limit their top speed to 25mph. Gyros were slightly faster than Sprees due to the fact they came with a two-speed transmission and a taller final drive ratio, but they still did 30mph at best. When I replaced the top-end parts I used a high-compression, Elite 50 piston and ring set (all dimensions were checked to insure compatibility). I also did some minor smoothing to the exhaust port and de-carboned the muffler. This Gyro does an honest 35mph with a 190lb. rider! The Elite piston and exhaust port work will not reduce reliability. I still have the original Gyro piston in excellent, serviceable condition. This Gyro looks great, is a blast to ride and runs better than new! I am a certified Honda mechanic and currently work as an aircraft technician.

To the left and at the bottom are pictures of the 1981 Honda Stream. I've never seen any mention of the Stream being sold in North America although there seem to be a few in Europe. What is apparent is that some two years later, the running gear showed up on the Gyro and the Stream became a forgotten bit of history. Too bad. 1981 NV50MC ~  3.8 PS@6500 RPM

May/2002~ I ran across an importer in California that has 3 different gyro models in stock including the Gyro canopy pictured at the top of this page. The website address is http://WWW.TPIMOTORSPORTS.COM
