Road legal KÜRZ RT1, you'll definitely be surprised at what this road bike has to offer. Improved more powerful designed engine combined with more above-industry standard parts which make the quality of this road-legal bike superior to its own class. This is the model that really lets you feel the grunt.

The KÜRZ RT1 150 is the ideal bike for riders taking the circuit track experience to the tarmac, a great solid feeling affordable buy for the rider. This is the model that really lets you feel the grunt.

The RT1 150 boasts a YX Racing 150cc 4-stroke engine, this version packs a massive punch being the beast of the RT1 range, also having higher gear ratios to achieve maximum top speed, yet still using its high torque to pull strong out of the bends. The upright, centred and aggressive riding position of a supermoto styled motorcycle allows exceptionally tight cornering with the lightweight agility and potent acceleration of a dirt bike.

Unlike motocross, the tarmac surface of supermoto provides phenomenal grip with the slick style Kenda tyres, allowing you to charge into corners and power straight out again with confidence and ease.

The kick start ensures you can get going quickly and easily wherever you find yourself. The headlight, tail lamp, indicators and LCD backlit speedometer adds to the RT1's versatility, all powered by a compact battery and located centrally to maintain a balanced bike.

Every feature of the KÜRZ RT1 has been carefully designed with racers in mind, lighter than traditional street bikes and with a more centred balance point, makes it easy for supermoto riders to hang the rear end out and come into corners sideways with the tyres smoking.

The KÜRZ RT1 150 has a 4 speed manual gearbox with gears being a simple arrangement of four up - (N-1-2-3-4) so no false neutrals.

With the new option to buy a set of E4 approved enduro tyres and wheels in addition, you can expand your horizons even more. Take your road bike to the dirt with a simple and fast wheel swap, increasing your presence and versatility with the front 17” and back 14” enduro style wheels. With the power from the engine this little beauty can take anything in its stride.
