2011 Honda CRF50F Overview

For 2011, Honda offers the CRF50F as a trial motorcycle with 49 cc on tap. The 2011 Honda CRF50F is built around a Single cylinder, four-stroke engine running SOHC valve actuation, a compression ratio of 10.0:1. Internally, bore and stroke are 39 x 41.4 mm. In everyday use, the 2011 CRF50F tips the scales at 49.9 kg, carries a 2.65-litre fuel tank, offers a seat height of 549 mm and spans a 914 mm wheelbase. That's roughly 31.5 kg lighter than the average trial motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2011 Honda CRF50F spec sheet below.

2011 CRF50F - Pros & Cons

Strengths

  • Accessible seat height: At just 549 mm, flat-footing at a stop is easy for most riders - a genuine confidence builder for less experienced owners.

Considerations

  • Carburetor fuelling: Carburetion is more hands-on than fuel injection - plan on periodic jetting and cleaning as part of routine ownership.
  • Modest fuel capacity: A 2.65-litre tank keeps things light but means budgeting for more frequent fuel stops on any longer ride.
  • Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.

Wear Points & Servicing Notes

Carburetor maintenance

Being carbureted, the CRF50F is more sensitive to stale fuel and altitude changes than a fuel-injected bike - a carb clean and rejet restores crisp throttle response after any extended lay-up.

Valve clearance checks

Valve clearances on SOHC-equipped engines like the CRF50F'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 Inverted telescopic fork up front and Single-shock 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

Chain final drive on the CRF50F means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.

Frame & chassis check

The Aluminium chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.

Low-speed handling

The CRF50F's 49.9 kg kerb weight makes low-speed control noticeably less effort than on a heavier machine.

CRF50F - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2011 Honda CRF50F 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 CRF50F settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a CRF50F's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.

Carburetor upkeep

A CRF50F that's sat unused is almost always a carb-cleaning job before it runs right again - float bowls and pilot jets first, since they clog before anything else.

Valve clearance service

There's no reliable seat-of-the-pants way to tell if a CRF50F'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.
