Mike Fickle’s custom 1968 Honda S90 won the Best MotoGiro Award sponsored by Martech Printing at the 2013 HoAME Vintage Motorcycle Rally. This little Honda certainly fits the bill, with just 90cc from its classic laid down single cylinder motor. One of the Honda’s it was said you’d meet the nicest people on, the intake and exhaust upgrades on this example at least make it sound mean.
Don’t know what a MotoGiro is? MotoGiro is a rally for vintage small bore bikes, originally started in Italy, that requires you to ride a bike of less than 305cc built in 1968 or before.
Clymer Girl and the crew didn’t have to go far to attend the HoAME show and rally, as it was just up the road at the Kansas City Airline History Museum in the Downtown Airport. The show was packed with classic vintage and antique motorcycles representing the best of British, German, Japanese, Italian, and American manufacturers. Some of the brands on display were Honda, Yamaha, Suzuki, BMW, Harley-Davidson, Triumph, BSA, Norton, Indian, Cushman, Vespa, Laverda, Lambretta, Ducati, Matchless, Zundapp, Moto Guzzi, and more. There was everything from 100% perfect restorations, to well worn bikes daily riders, to full-on customized cafe racers, choppers, bobbers, dirt bikes, road racers – any type or style of motorcycle you could image. As part of the museum’s permanent exhibits, there were also vintage propeller driven passenger planes, including a Douglas DC-3, a Martin 404, and, the pride of their collection, a 1958 Lockheed Super Constellation.
It was only a few years after Honda hit the US market that they first introduced the OHC laid down single that made them a household name in the 1960s. Derived from the 50cc pushrod motor first used in the Super Cub step-thru scooter, by 1964 the motor was making 8 horsepower from 90cc and had gained a 4th gear. The S90 used a stamped and welded steel frame much like the step-thru, but with the tank mounted up top like a real motorcycle. Also like a real motorcycle it gained a manual clutch, instead of the twist and go automatic set up on the earlier scooters. Top speed was said to be over 60 mph, if the rider was small and could make themselves aerodynamic.

If you have a classic Honda with the laid down single, be it a Super Cub, a Passport, a Trail 90 or one of these, you can find all the repair info in the Honda 50-110cc OHC Singles manual or the Vintage Collection Series Four-Stroke Motorcycles manual.
