Kawasaki 2021 KX250 for Sale at Ultimate Kawasaki Gold Coast in Nerang, QLD | Specifications and Review Information


A NEW KIND OF KX: KX250-BASED CROSS-COUNTRY RACER

The KX brand is no longer just for motocross! With the release of the 2021 KX250X, Kawasaki brings KX performance to the cross-country scene. Based on the championship-winning KX250 motocrosser, the new cross-country racer boasts an arsenal of factory-style features along with the engine and chassis performance that makes the KX250X such a potent off-road contender. X specific tuning for the engine, suspension and brakes, complemented by a 21"/18" wheel combination fitted with enduro-type tyres, and convenient standard features like a side stand and skid plate make the new KX250X even more attractive for cross-country competitors.

FEATURES

  • Fuel-injected 249cm3 liquid-cooled 4-stroke, single cylinder engine.
  • New slim, ergonomic bodywork KX450 styling with long, smooth surfaces and flatter tank-seat line.
  • Revised, KX450-based frame and KX450 Swingarm offer improved handling and increased rear wheel traction.
  • KX450 Hyrdaulic Clutch offering more direct feel and light lever action for more consistent feeling.
  • Updated Race Ready Suspension optimised for increased feedback on aggressive trails.
  • Ease of use with Electric Start and lightweight compact Li-ion battery.
  • Front 21" and Rear 18" wheels and enduro-type tyres are well suited to the cross country riding conditions.
  • High performance KYB 48mm dia inverted coil-spring fork (with Kashima Coat) matched to a new KYB shock unit.
  • Factory-style 28.6mm Renthal Aluminium Fatbar reduces vibration and shock transmitted to the rider.

2021 KX250 - FACTORY-STYLE ENGINE COMPONENTS AND TUNING

FACTORY-STYLE ENGINE COMPONENTS AND TUNING

Despite the 2020 KX250 already benefitting from a significant power increase thanks to its adoption of finger-follower valve actuation like the KX450, additional changes for 2021 raise peak power even further and enable an even higher rev limit, while significantly increasing low-mid rpm performance. As before, dual injectors, downdraft-style intake, and race inspired tuning and parts add to performance.
MORE-RACE-WINNING HIGH-RPM POWER

MORE-RACE-WINNING HIGH-RPM POWER

The new engine boasts an increase in peak power of approximately 1.0 kW (1.4 PS), and the rev limit increases a further 350 min-1 to 14,500 min-1. A significantly more robust low-mid range is complemented by strong high-rpm performance that gives riders an advantage on the straights, and, when combined with a higher rev limit, makes it easier to tie corners together for quicker lap times
2021 KX250 - FACTORY-RACER ENGINE TUNING

FACTORY-RACER ENGINE TUNING

Like the KX450, the KX250 features a valve train designed by Kawasaki's World Superbike engineers. Finger-follower valve actuation enables a higher rev limit and more aggressive cam profiles - both contributing to high-rpm performance.
2021 KX250 - HYDRAULIC CLUTCH

HYDRAULIC CLUTCH

Like the KX450, a hydraulic clutch offers direct feel and light lever action. Less play as the clutch heats up during heavy use results in more consistent feeling. The use of coned-disc springs contributes to lighter clutch actuation when the lever has been pulled in, and a wider clutch engagement range, which facilitates control (especially when half-clutching).
2021 KX250 - ELECTRIC START & BATTERY

ELECTRIC START & BATTERY

Being able to restart an engine quickly during a race can mean the difference between keeping your lead, or having to fight your way back through the pack. Electric start makes restarting the engine as easy as pushing a button. Lightweight, compact Li-ion battery helps keep weight to a minimum.
2021 KX250 - LIGHTWEIGHT FRAME

LIGHTWEIGHT FRAME

An evolution of the current design, the new frame offers a better overall rigidity balance. While many parts are common with the KX450's frame, the cast parts (like the shock tower mount and engine hangers) were designed specifically for the needs of the KX250.
2021 KX250 - ENGINE TUNING

ENGINE TUNING

Adjusting engine settings to suit conditions is simple with the three DFI couplers. Plug-and-play style system is quick, easy and stress-free. Each of the three maps can be reprogrammed using the optional accessory KX FI Calibration Kit.

  1. MX Hard conditions (default)
  2. MX Standard conditions
  3. MX Soft conditions.
2021 KX250 - STEERING HEAD & SWINGARM UPDATE

STEERING HEAD & SWINGARM UPDATE

Steering head area with optimised rigidity, main frame rails with revised cross-sections, and a revised line for the swingarm brackets contribute to the overall rigidity balance. Wider lower frame rails also contribute to overall rigidity balance. KX450 swingarm delivers the rigidity to match the frame, and contributes to increased rear traction. Chassis balance and settings were all set to suit race-experienced riders.
2021 KX250 - RACE READY SUSPENSION

RACE READY SUSPENSION

High-performance KYB Ø48 mm inverted coil-spring fork handles suspension duties up front. Its large-diameter inner tubes enable the use of large Ø25 mm damping pistons, delivering smooth action and firm damping. Lower triple-clamp with revised rigidity and revised linkage ratios contribute to increased absorption and damping performance.
2021 KX250 - STRONG BRAKING PERFORMANCE

STRONG BRAKING PERFORMANCE

New KX450 front master cylinder adds to the high level of control and feedback from the front brake. A smaller-diameter rear disc Ø240 mm offers performance optimised for the KX250. The stylish discs contribute to both sporty looks and a high-quality appearance.
2021 KX250 - RACER-FRIENDLY ERGONOMICS

RACER-FRIENDLY ERGONOMICS

Factory-style Ø28.6 mm (1-1/8") Renthal aluminium Fatbar, a popular aftermarket part, is now a standard feature. The thicker handlebar helps reduce vibration and shocks transmitted to the rider, while the new grip position (19 mm lower, 8 mm 10 closer) helps put the rider in a position that makes it easier to weight the front wheel.
2021 KX250 - FACTORY STYLING

FACTORY STYLING

Complementing the KX250's sleek new bodywork, factory-style graphics ensure it is the sharpest looking bike in the paddock and further reflect its highly-tuned performance. Coloured highlights on the suspension adjusters and engine oil cap and generator cover plugs contribute to a distinctive Kawasaki look.
SLIM, ERGONOMIC BODYWORK

SLIM, ERGONOMIC BODYWORK

The narrow frame and minimalistic bodywork offer a slim riding position that facilitates control. A low, flat tank/seat design makes it easier to sit farther forward, and long, smooth surfaces make it easy to slide back and forth.
2021 KX250 - ADJUSTABLE ERGONOMICS

ADJUSTABLE ERGONOMICS

A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference.
