Description
The Excel Takasago aluminum alloy rim is the benchmark in off-road racing rim technology. Every Excel MX rim is engineered and designed to perform in extreme hostile environments where other rims routinely fail. In fact, Excel has won more Motocross and off-road championships - worldwide - than all competitors combined! Part of the secret is in our exclusive 7000 series aluminum alloy which has a 50% higher yield strength than our competitor's 6 series aluminum. Also, exclusive know- how in extrusion design, complex multi-step forming, advanced robotics welding, and in hard anodizing such a tough and complex material is key to Excel's strength and world market dominance. They are the choice of all Factory Works and Privateer Teams worldwide and the choice of OEM builders such as Honda, Kawasaki, KTM, Suzuki and Yamaha.

Vehicle Information
Yamaha YZ80 Dirt Bike (1974-2001)
The Yamaha YZ80, a celebrated two-stroke motocross dirt bike, was produced from 1974 to 2001, eventually succeeded by the YZ85. Throughout its production, the YZ80 evolved significantly, transforming from an air-cooled, twin-shock model with drum brakes to a liquid-cooled, monoshock machine equipped with disc brakes. Yamaha did not offer traditional "trims"; instead, model years were often designated with a letter (e.g., YZ80A, YZ80E), indicating yearly updates to the single motocross model. Key evolutionary stages include the introduction of liquid cooling in 1982, a front disc brake in 1986, and a major overhaul in 1993. This 1993 redesign was comprehensive, featuring a larger chassis, new bodywork, dual disc brakes, inverted front forks, and a significantly revised engine. This architecture remained largely consistent until the end of its production in 2001. FAQ:
Q: How do I know if this part fits my YZ80?

Maintenance
| Component | Interval | Details |
| Engine Oil (Transmission Oil for 2-Strokes) | Every 5 to 15 hours | Engine oil for 2-strokes refers to transmission oil. The engine itself is lubricated by fuel-oil premix. Change more frequently for aggressive or race riding (5-7 hours) and less for recreational riding (10-15 hours). |
| Oil Filter | Not applicable | 2-stroke engine, does not have a traditional engine oil filter. Transmission oil should be changed at the interval listed above. |
| Drive Belt | Not applicable | The Yamaha YZ80 uses a chain drive system, not a belt. The chain should be regularly cleaned, lubricated, and inspected for proper tension and wear. |
| Spark Plug | Inspect and replace every 30 hours | Replace during pre-season service (for 1974 models). It is recommended to always carry a spare plug for 2-strokes. |
| Air Filter | Clean every 2 to 10 hours | Clean more frequently (every 2-3 hours) in dusty or muddy conditions. Wash, dry, and re-oil the foam filter, and inspect the intake boot. |
| Coolant | Annual inspection | Applicable to liquid-cooled models (from 1982). Earlier models (1974-1981) were air-cooled and do not use coolant. |
