2011 Yamaha PW50 Overview

The 2011 Yamaha PW50 is an enduro / off-road motorcycle built around 49 cc of displacement. Under the tank sits a Single cylinder, two-stroke engine running Single Overhead Cams (SOHC) valve actuation, a compression ratio of 6.0:1. The bore and stroke measures 40 x 39.2 mm. From a practical standpoint, 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.

2011 PW50 - Pros & Cons

Strengths

Fuel injection: The fuel injection injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.
Accessible seat height: At 485 mm, the seat height is approachable for a wide range of rider heights and builds confidence in low-speed manoeuvring.

Considerations

Age-related wear: As with any used PW50, a thorough pre-purchase inspection covering consumables, service history and tyres is always recommended.

Owner Experiences & Common Issues

Throttle response and fuelling

The fuel injection on the 2011 Yamaha PW50 is generally well-regarded. Some owners note a slight hesitation at small throttle openings when cold, which clears once the engine reaches operating temperature. A quick visual check of the injector connectors during routine servicing is good practice on higher-mileage examples.

Valve clearance checks

Single Overhead Cams (SOHC) engines should have valve clearances checked at the manufacturer's specified interval. Owners report that clearances can tighten over time on higher-mileage bikes, leading to slight ticking from the top end. Catching it early keeps the job simple and avoids more costly remediation.

PW50 - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2011 Yamaha PW50, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained PW50 should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any PW50. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. The sump holds 2.40 litres, so budget for that volume of quality motorcycle-specific engine oil. Always use the correct viscosity grade as specified in the owner's manual.

Fuel system care

The PW50's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.

Valve clearance service

Check that valve clearances have been adjusted at the correct intervals on any used PW50. This is a job many owners skip because the bike does not immediately feel wrong - but tight clearances accelerate valve seat wear. Ask for proof it has been done.
