Benelli 1130 TRE-K 2008 — Specifications

When Benelli decided to graft the TNT’s three-cylinder engine onto a high chassis, the idea was all provocation. Neither truly trail, nor supermotard, nor roadster, the 2008 TRE-K 1130 invents its own category, somewhere between a stage beast and a catalog oddity. The result is a motorcycle that is as disconcerting as it is fascinating, and one that deserves serious consideration.

Visually, the TRE-K asserts its presence without complex. The sculpted tank, the trellis frame made of reinforced steel tubes, the tubular swingarm, all form a coherent, almost aggressive whole that looks good from every angle. The seat, announced at 810 mm, seems even higher in practice, which immediately rules out shorter riders. The 205 kg dry weight is manageable when in motion, the machine is more agile than it appears when stationary, but you have to contend with 240 kg when fully fueled and a height that demands a certain respect during slow maneuvers.

What really strikes you from the first few minutes of riding is the engine. The 1130 cm3 three-cylinder develops 125 horsepower at 9000 rpm and a torque of 111.8 Nm at 6750 rpm, figures that you immediately feel in your wrists. Compared to the original TNT version, the engine has been slightly revised to favor mid-range torque, and the effect is striking on the open road. The sound is raspy, mechanical, almost choleric, unlike the smooth song of a Japanese four-cylinder. The six-speed gearbox responds precisely, and the two injection maps available offer theoretically interesting modulation, even if the difference between the two modes remains subtle in practice. Some stumbles are noticeable when re-applying the throttle, a sign that the electronic management would benefit from refinement.

The braking is powerful, the two 320 mm discs at the front with four-piston calipers stop the machine without discussion, but the bite lacks progressiveness for a motorcycle of this temperament. At the rear, the 240 mm disc locks the wheel a little quickly, even if the motorcycle remains perfectly controllable in these situations. The original tires, road-trail profiles, are the real weak point of the TRE-K in sporty use. A few light slides in corners are enough to convince you to quickly invest in a sport tire adapted to the 125 horsepower available. The suspension, an inverted 50 mm fork with 120 mm of travel and a 115 mm rear mono-shock, are relatively firm for a trail, but correctly filter out everyday road imperfections.

The ergonomics, on the other hand, reveal some typically Italian flaws. Finding the neutral position requires patience and an educated foot. The side stand is a pain to grab. The triangular mirrors are beautiful, but their field of vision is ridiculous. And some body panels vibrate disturbingly at acceleration, which mars the appearance of a motorcycle costing 12,660 euros. It’s not a deal-breaker, but it’s a shame on an engine that otherwise shows a certain care in its structural construction. The TRE-K is clearly not intended for grand touring, unlike a Yamaha TDM or a Honda Varadero which target the same apparent niche. It is aimed at those who want the raw character of the TNT packaged in a slightly more civilized format, more versatile on paper, without ever losing that nervousness that makes every outing stimulating. For enthusiasts of sharp mechanical sensations, it is a sincere proposition. For travelers seeking comfort and practicality, it is better to look elsewhere.
