For the 1968 model year, the Yamaha AS1 motorcycle has a listed dry weight of 216.1 lb (98 kg).
Yamaha AS1 weight overview
This is a genuinely light bike. That usually makes parking, pushing it around a garage and catching small low-speed balance errors easier than on larger motorcycles. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.

Yamaha AS1 weight FAQ
How much does the Yamaha AS1 weigh?
The source data gives 216.1 lb (98 kg) as dry weight. A fueled, road-ready bike will weigh more than this figure.
What does a full tank of gas weigh on the Yamaha AS1?
A full tank works out to about 15.5 lb (7 kg) from the listed 2.5 US gal (9.46 L) capacity. Actual fuel density varies slightly, so treat it as a practical estimate.
What does the Yamaha AS1 weigh with a 180 lb rider?
The approximate combined total is 396.1 lb (179.6 kg) with a 180 lb rider, based on the representative dry weight used on this page.
Is the Yamaha AS1 strong for its weight?
The calculated range is 6.94 hp per 100 lb. This ratio is usually more informative for acceleration comparisons than horsepower alone.
How much heavier will the Yamaha AS1 be than its dry weight?
Do not treat dry weight as curb weight. Adding the listed fuel capacity alone produces roughly 231.6 lb (105 kg); the true ready-to-ride figure can still differ because dry-weight definitions vary.
What is the Yamaha AS1 torque-to-weight ratio?
Available data gives 4.34 lb-ft per 100 lb. That ratio helps explain how strong the engine is relative to the bike’s mass, especially at lower speeds.
How large is the Yamaha AS1 engine for its weight?
The model has about 0.58 cc per lb in the available data. This simply shows how much engine displacement there is for each pound of motorcycle weight.
Is the Yamaha AS1 easy to move around by hand?
By scale weight it is light, so backing up, garage movement and slow-speed corrections should require less effort than on heavier bikes. Geometry still matters.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition. Calculated fuel-weight and ratio figures on this page are estimates derived from the supplied specifications.
