2015 KTM 50 SX MINI

Posted on by  

The KTM SX MINI was especially designed for kids (4-10 years old) and features an ergonomic riding position, an easy to use engine and a sporty style borrowed from its bigger sibling.

At the heart of the bike sits a 49 cc, 1-cylinder, 2 - stroke, water - cooled engine with reed intake which is combined with a 49.0 Cc unit.

The KTM 50 SX Mini rides on ultra - light, black anodised aluminium rims that help the rider deal great with any type of terrain. The wheels are wrapped in a pair of modern tyres from MAXXIS which further enhance the bike’s performances on tough trails.

The KTM 50 SX MINI’s speed is kept under control by all-round disc brakes which measure 160 mm and feature four-pot brake calipers up front and two-pot brake calipers at the rear.

Control that’s child’s play

Suspension/damping
Both the rear shock absorber and the 35 mm upside-down fork are high-quality products from WP Suspension and guarantee ultimate damping and responsiveness.

WP chassis
A high quality, upside-down telescopic fork from WP Suspension, featuring 35 mm diameter outer tubes and 100 mm suspension travel, ensures outstanding ride stability. A WP shock absorber connected directly to the swingarm also supplies 171 mm of suspension travel at the rear wheel.

Adjustable automatic transmission
The centrifugally controlled, multi-disc automatic clutch developed by KTM delivers easily controllable acceleration and makes riding the 50 SX Mini the easiest thing in the world. Furthermore, it can still be quickly and easily adjusted to the specific requirements of both track and rider using the "KTM clicker system" - in a matter of seconds and with no special tools required.

Made-to-measure performance

Optional restrictor kit
For absolute beginners, the engine power can be restricted to a moderate 5.5 hp with a kit from the PowerParts range.

Radiator
Just like the big KTM bikes, the 50 SX Mini is also equipped with water cooling that even cools the crankcase. Generously dimensioned radiators ensure excellent heat dissipation and therefore high reliability, even under extreme loads.

Clutch
The centrifugally controlled, multi-disc automatic clutch developed by KTM delivers easily controllable acceleration and makes riding this bike the easiest thing in the world. It can be adjusted in no time at all, without special tools, to the specific requirements of both track and rider.

Engine
The modern, extremely compact, 2-stroke engine sets the benchmark in its class with its very controllable power. Thanks to the 3-shaft concept, the crankshaft is close to the bike’s centre of gravity. This not only benefits the handling; it also provides a flow-optimised inflow angle at the intake membrane – a prerequisite for maximum performance.

Top quality.

Brakes
Both at the front and rear, state-of-the-art hydraulic disc brakes from FORMULA ensure best possible retardation. The exclusive, self-cleaning Wave brake discs stand for the ultimate in race technology and outstanding safety.

Water cooling
The liquid-cooling system of the KTM 50 SX Mini, with two large radiators and additional cooling for the crankcase, prevents the engine overheating, even under the most extreme loads. The smallest KTM is even unfazed by coming to blows with the ground.

Wheels
Just like the big factory bikes, the 50 SX Mini is equipped with ultra-light, black anodised aluminium rims that easily withstand even the biggest of jumps. The 50 SX is now equipped with the very latest generation tyre from MAXXIS, featuring a profile that guarantees optimum grip on every surface.

Top ergonomics

Graphics
The graphic design derived from that of the full-size SX bikes makes the little KTM even cooler. Its frame has a hardwearing plastic coating in anthracite metallic.

Handlebar
The ergonomic Renthal handlebar made from a high-quality aluminium alloy ensures the highest levels of stability and safety. A Renthal crash pad around the centre brace protects the rider from hard knocks.
