On the performance side, it delivers 6.30 of torque. On the road, the 2008 PW80 tips the scales at 57 kg, carries a 4.90-litre fuel tank, offers a seat height of 635 mm and spans a 1,055 mm wheelbase. The full 2008 Yamaha PW80 spec sheet below covers every technical detail, from suspension travel to tyre sizes.
2008 Yamaha PW80 compared with other bikes in the Enduro / Off-Road category
We checked the recorded figures for the 2008 Yamaha PW80 against up to 1434 bikes in the Enduro / Off-Road category in our database, counting each model once at the model year nearest to this one.
- Only 7 of the other 1145 bikes in the Enduro / Off-Road category have a lower seat height than the 635 mm of the PW80.
- With 79 cc, the PW80 has the joint 18th smallest engine displacement of 1434 bikes in the Enduro / Off-Road category, 84% below the category average of 486 cc.
- Narrowing the field to the 484 models within five model years of it, the seat height of 635 mm is lower than that of 476 of the other 483.
Versus the 2007 model
The figures we track are unchanged from the 2007 model: displacement and seat height all match.
2008 PW80 - Pros & Cons
Strengths
-
📏
Accessible seat height: A 635 mm seat height keeps this manageable for most riders, which helps confidence at parking-lot speeds.
Considerations
-
🔧
Carburetor fuelling: Expect to spend more time keeping the carbs in tune, especially after long storage periods or a change in altitude.
-
🛑
Drum rear brake: Rear braking comes from a drum, not a disc - it does the job but won't match the feel or fade resistance of newer equivalents.
-
⛽
Modest fuel capacity: Range between stops is limited by the 4.90-litre tank - plan fuel stops accordingly on longer routes.
-
⚙️
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.
Wear Points & Servicing Notes
Carburetor maintenance
Carburetors on the PW80 need periodic attention - pilot jets and float needles are the first parts to gum up after the bike sits, and the first thing to check if idle or throttle response degrades.
Suspension condition on used examples
The PW80's suspension runs Telescopic forks at the front. The rear uses Swingarm. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The PW80 uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.
Frame & chassis check
Built around a Steel tube backbone, the PW80's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.
Low-speed handling
57 kg keeps the PW80 easy to move around in tight spaces, car parks and on the stand alike.
PW80 - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2008 Yamaha PW80 with its 79 cc enduro / off-road, cover the fundamentals: service book and oil change history, drivetrain wear, and any sign of oil weeping around the casings. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 18 years old, this enduro / off-road is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Cold-starting it yourself tells you a lot - a healthy PW80 should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects the PW80's 79 cc single cylinder like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). With a 6.6:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
Carburetor upkeep
Deposits in the carbs are the usual culprit behind poor running on a stored PW80 - strip and clean the float bowls before the first start. Pilot jets clog first and get overlooked most, so make a point of checking them.
