Rat bike engineering: sound joint between sections of exhaust pipe without the use of welding equipment. The concept of keeping a motorcycle in at least minimally operational condition without consideration for appearance has probably characterized motorcycle ownership since its earliest days. [ 2 ]
L – Rupp manufactured two L-series dirt bikes in 1973, the L80 and L100. Both bikes used 2-cycle Fuji engines, in 80 and 100cc sizes. They were equipped with four- and five-speed manual transmissions, respectively. SS – The SS-5 was Rupp's only dirt bike that used a Tecumseh engine and automatic transmission. The engine was a Tecumseh HS50 ...
On August 6, 2015, the daredevil stunt performer Doug Danger [22] at the Sturgis Bike Rally at the Buffalo Chip, broke Knievel's record for most cars jumped on a XR-750 with 22 cars. Knievel attempted this feat of 22 cars in Monroe, Washington on September 1, 1972, and cleared 21 cars but landed on the safety deck covering the 22nd car.
The VRSC was introduced in 2001 in a single model called the V-Rod aiming to compete against Japanese and American muscle bikes. The V-Rod's Revolution engine was developed for road use by Porsche Engineering with the aid of a few Harley-Davidson engineers [6] [7] [8] from Harley-Davidson's VR1000 V-twin racing bike engine.
Joey Dunlop coming down Bray Hill, Isle of Man in the 1992 Senior TT race, on his Honda RC30. While being inspired by the Honda RVF endurance racer (not to be confused with the Honda RVF750 RC45) the VFR750R instead had its engine based on the 1986-7 VFR750F (RC24). The engines are almost identical externally, the only visible differences being ...
For their Ultra-Lightweight class (50 cc) Grand Prix race bikes during the 1964, 1965 and 1966 race seasons, Honda re-introduced the 1920s format of cable-actuated caliper rim brakes with shoes/blocks directly acting on the aluminium rim-sides (alloy wheel rim), creating almost a 'consumable' item from the wheels, but dispensing with heavy ...
Hodaka Trail Bikes. Hodaka was a joint Japanese and American company that manufactured motorcycles from 1964 to 1978. Close to 150,000 motorcycles were produced within that time. Prior to 1964 Hodaka made engines for the Yamaguchi motorcycle brand. [1] The worldwide distributor of Hodakas was PABATCO, for Pacific Basin Trading Company.
Note that, on a bicycle, as rake angle increases, head angle decreases. Trail can vary as the bike leans or steers. In the case of traditional geometry, trail decreases (and wheelbase increases if measuring distance between ground contact points and not hubs) as the bike leans and steers in the direction of the lean.
