MORE POWER, SMOOTH AND CONTROLLED

This model continues to evolve and reaches its peak this year with an entire and profound improvement of the engine part, that seeks to bring to perfection our revolutionary technological concept for more intuitive riding, sensation and power than before and adapt to every circumstance and to the most aggressive riding through our experience in global competition.

The engine of the new TR280i is the culmination of two years of development by the Ossa Race Team “ORT”. Since the revolutionary birth of your engine its unique characteristics have been praised and acknowledged for the flawless behaviour of its electronic injection system regardless of temperature or altitude. The engine possesses unsurpassed smooth and controllable power to enhance any type of riding at any level. For 2014 the TR280i receives a new cylinder head completely redesigned and higher compression to provide a more efficient combustion chamber improving power delivery and pollution emissions. A new “EFI” electronic fuel injection mapping capitalizes on the virtues of the new thermal cycle, to add, improvements to the crankshaft and crankcase have reduce internal friction and vibration. The ECU has been relocated for easier access and increase the air box volume.

HIGHEST QUALITY SUSPENSION

The suspension of the TR280i has been of the highest quality and unsurpassed since the birth of the model. Based on development work by the Ossa Race Team the suspensions have been further improved with a more progressive setting, in addition the stop of the Ohlins rear suspension has been improved to improve behaviour and rebounding.

NEW LOOK AND ERGONOMICS

The TR280i 2014 receives a stunning makeover with a new design seat base and rear mudguard to provide an overall lower profile. The ergonomics are more streamlined and compact providing greater freedom for the pilot. The overall feeling of the OSSA TR280i has been redesigned to allow operation of its controls to be more precise and intuitive to the rider.

MORE RELIABLE AND EASY TO MAINTAIN

With the invaluable experience of the Ossa Race Team the reliability and maintenance TR280i has vastly improved as well as performance. We have worked hard on the gearbox and introduced new tooth design and heat treatment for durability, also redesigned and improved are the internals of the water pump.

The TR280i will feel as one with your body. The new accelerator has less travel and a more direct and quick feel. The hydraulic clutch internal diameter has been increase and the clutch plate design improved. The rear brake hose diameter is increased to provide an improved feel and more consistent performance. A stunning new decal design completes the TR280i in green, sliver and yellow.
