2016 KTM 65 SX Overview

The 2016 KTM 65 SX is a cross / motocross motorcycle built around 64.85 cc of displacement. Under the tank sits a Single cylinder, two-stroke engine. The bore and stroke measures 45 x 40.8 mm. From a practical standpoint, the 2016 65 SX tips the scales at 53 kg, carries a 3.50-litre fuel tank, offers a seat height of 750 mm and spans a 1,137 mm wheelbase. That's roughly 45.6 kg lighter than the average cross / motocross motorcycle in our database. Scroll down for the complete 2016 KTM 65 SX spec sheet covering every technical detail from suspension travel to tyre sizes.

2016 65 SX - Pros & Cons

Strengths

Accessible seat height: At 750 mm, the seat height is approachable for a wide range of rider heights and builds confidence in low-speed manoeuvring.

Considerations

Carburetor fuelling: Carbureted engines need occasional jetting attention and can be reluctant in cold weather or at altitude compared to modern fuel-injected alternatives.
Modest fuel capacity: The 3.50-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.

Wear Points & Servicing Notes

Carburetor maintenance

The 65 SX uses carburetion rather than fuel injection, which means jetting is altitude- and temperature-sensitive and benefits from a clean-and-rejet after extended storage or an exhaust change.

Brake disc and pad wear

The Single disc. Four-piston calipers. Wave brake discs. front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the 65 SX runs WP upside-down ? 35 mm and WP shock absorber at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Final drive maintenance

Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.

Frame & chassis check

The frame is Central-tube frame with double-cradle - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.

Low-speed handling

At just 53 kg, the 65 SX is light enough to manhandle easily at a standstill - one of the practical advantages of its class.

65 SX - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2016 KTM 65 SX, 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 65 SX 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 65 SX. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.

Carburetor upkeep

Keep the carburetors clean and free of deposits. If the 65 SX has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.
