2020 Kawasaki KX65 Overview

For 2020, Kawasaki offers the KX65 as a cross / motocross motorcycle with 64.7 cc on tap. The 2020 Kawasaki KX65 is built around a Single cylinder, two-stroke engine, a compression ratio of 8.4:1. Internally, bore and stroke are 44.5 x 41.6 mm. In everyday use, the 2020 KX65 tips the scales at 60 kg, carries a 3.79-litre fuel tank, offers a seat height of 759 mm and spans an 1120 mm wheelbase. That's roughly 49.9 kg lighter than the average cross / motocross motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2020 Kawasaki KX65 spec sheet below.

2020 Kawasaki KX65 compared with other bikes in the Cross / motocross category

Measured against other bikes in the Cross / motocross category in our database (up to 224 models, one entry per model), the 2020 Kawasaki KX65 comes out as follows.

  • With 60 kg, the KX65 has the joint 2nd lightest wet weight of 129 bikes in the Cross / motocross category, 45% below the category average of 109.9 kg.
  • Engine displacement of 65 cc is smaller than that of 212 of the other 223 bikes in the Cross / motocross category.
  • Only 18 of the other 199 bikes in the Cross / motocross category have a lower seat height than the 759 mm of the KX65.
  • Narrowing the field to the 63 models within five model years of it, the wet weight of 60 kg is lighter than that of every one of the other 62.

Versus the 2019 model

The figures we track are unchanged from the 2019 model: wet weight, displacement and seat height all match.

2020 KX65 - Pros & Cons

Strengths

  • Strong front braking: The single disc front brake bites hard and stays consistent - a solid foundation whether it's stock or upgraded with braided lines.
  • Accessible seat height: At just 759 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 3.79-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 KX65 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.

Brake disc and pad wear

Single disc with hydraulic up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Suspension condition on used examples

Suspension duties are handled by 33 mm telescopic fork with 4-way rebound damping up front and Bottom-Link Uni-Trak with gas-charged shock, adjustable preload and stepless rebound damping 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 KX65 means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.

Frame & chassis check

The Tubular, semi-double cradle 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 KX65's 60 kg kerb weight makes low-speed control noticeably less effort than on a heavier machine.

KX65 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2020 Kawasaki KX65 with its 64.7 cc cross / motocross should cover the same ground every time: service history, drivetrain condition, and any oil seepage 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 6 years old, this cross / motocross is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Start it from cold if you can - a well-kept KX65 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for the KX65's 64.7 cc single cylinder, two-stroke - keep to the manufacturer's interval rather than stretching it. With an 8.4:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Use the viscosity grade the manual specifies, not whatever's on sale.

Carburetor upkeep

A KX65 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.
