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 a 1120 mm wheelbase. That's roughly 38.6 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 KX65 - Pros & Cons

Strengths

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. 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 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 KX65 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a KX65'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 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.
