2017 KTM 250 SX-F Overview

The 2017 KTM 250 SX-F is a cross / motocross motorcycle built around 249.91 cc of displacement. Under the tank sits a Single cylinder, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation. The bore and stroke measures 78 x 52.3 mm. From a practical standpoint, the 2017 250 SX-F tips the scales at 98.2 kg, carries a 7-litre fuel tank, offers a seat height of 960 mm and spans a 1,485 mm wheelbase. Scroll down for the complete 2017 KTM 250 SX-F spec sheet covering every technical detail from suspension travel to tyre sizes.

2017 250 SX-F - Pros & Cons

Strengths

Factory engineering: The 2017 KTM 250 SX-F represents KTM's engineering at the time, with a specification built around real-world usability.

Considerations

Tall seat height: The 960 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
Modest fuel capacity: The 7-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

Valve clearance checks

Double Overhead Cams/Twin Cam (DOHC) valve actuation on the 250 SX-F means clearances should be checked at the manufacturer's specified interval - they can tighten as mileage accumulates, and a light top-end tick is usually the first sign.

Brake disc and pad wear

The Single disc. Brake calipers on floating bearings 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 250 SX-F runs WP-USD, AER 48, ? 48 mm and WP shock absorber with linkage 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 25CrMo4 steel central-tube frame - 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 98.2 kg, the 250 SX-F is light enough to manhandle easily at a standstill - one of the practical advantages of its class.

250 SX-F - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2017 KTM 250 SX-F, 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 250 SX-F 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 250 SX-F. 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.

Valve clearance service

Check that valve clearances have been adjusted at the correct intervals on any used 250 SX-F. A bike with clearances out of spec doesn't always feel obviously wrong - but tight clearances accelerate valve seat wear. Ask for service documentation proving it's been done.
