2011 Yamaha PW50 Overview

For 2011, Yamaha offers the PW50 as an enduro / off-road motorcycle with 49 cc on tap. The 2011 Yamaha PW50 is built around a Single cylinder, two-stroke engine running Single Overhead Cams (SOHC) valve actuation, a compression ratio of 6.0:1. Internally, bore and stroke are 40 x 39.2 mm. In everyday use, the 2011 PW50 tips the scales at 38.6 kg, carries a 200.61-litre fuel tank and offers a seat height of 485 mm. That's roughly 159.4 kg lighter than the average enduro / off-road motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2011 Yamaha PW50 spec sheet below.

2011 PW50 - Pros & Cons

Strengths

  • Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
  • Accessible seat height: At just 485 mm, flat-footing at a stop is easy for most riders - a genuine confidence builder for less experienced owners.
  • Large fuel range: With a 200.61-litre tank, this isn't a bike you'll be stopping for fuel every hour - a real asset on longer trips.
  • Low-maintenance final drive: Shaft drive (cardan) final drive is about as close to maintenance-free as motorcycle drivetrains get.

Considerations

  • Age-related wear: No particular mechanical concern flags for the PW50 - condition on any used example comes down to how well it's been looked after.

Wear Points & Servicing Notes

Fuelling & injector care

Fuelling on the PW50 comes from fuel injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.

Valve clearance checks

Valve clearances on Single Overhead Cams (SOHC)-equipped engines like the PW50's drift slowly with mileage rather than failing suddenly - sticking to the service interval keeps it a non-issue.

Suspension condition on used examples

Suspension duties are handled by Telescopic fork up front and Unit swingarm at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Final drive maintenance

Shaft final drive on the PW50 removes chain and belt maintenance entirely - the trade-off is a little extra unsprung weight and periodic gear-oil changes.

Low-speed handling

The PW50's 38.6 kg kerb weight makes low-speed control noticeably less effort than on a heavier machine.

PW50 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2011 Yamaha PW50 should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept PW50 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a PW50's engine - keep to the manufacturer's interval rather than stretching it. The sump holds 2.40 litres, so budget for that volume of quality motorcycle-specific engine oil. Use the viscosity grade the manual specifies, not whatever's on sale.

Fuel system care

Injector systems like the PW50's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.

Valve clearance service

There's no reliable seat-of-the-pants way to tell if a PW50's valve clearances are in spec - a light top-end tick is the only real warning sign, and by then some wear has already happened. Service records are the only proof.
