Listen carefully and you’ll hear it. Light, yet divinely powerful, the Tramontana is coming.
Chassis development team members at Triumph have spent the past four years working in secret on what they believe is the ultimate off-road Scrambler with zero compromises.
Named after the north wind that sweeps powerfully across the Pyrenees into Spain – hence tra-montana – it has been designed to satisfy the dual needs of real off-road scrambling with big capacity.
A three-man team led by test rider and engineer brothers David and Felipe Lopez, have worked on the project in their own time and for their own satisfaction with some support from the factory, knowing it will never go into production. The starting point was the 270 crank parallel twin and its excellent levels of traction, good spread of torque and intuitive chassis character to guarantee a fun ride on forest tracks.
But David admitted: “It wasn’t until the Tiger 800XC development process that we understood the real off-road potential of big capacity bikes when they were purposely developed for it. “Our off-road background was more related to light bikes such as trials and enduro, so we were surprised by the pleasure of riding big bikes in challenging conditions and terrains.” Using the classics range as a base, they set about fulfilling a long-held dream of personalising one in the form of a high-performance cafe racer. They approached it as they approach every other chassis development project… developing it by riding and for riding.
Everything considered, nothing ruled out… that was the team’s approach as they worked through the night on the prototype mule.
Different geometries, suspension types, wheel sizes, ergonomics and engine configurations were examined, just as they are for a production bike. This time though every development decision taken had just one aim – the quest for the perfect off-road performance. After paring the Tramontana back to nothing, the guys put each stage through its paces in a series of configurations, starting from the most conservative to maintain the classic look.
But with performance always in mind, the end product was a far more modern-retro style that mixes the essence of the Scrambler and sixties Triumphs provided by the parallel twin and the mono-spine twin-shock frame, with the high performance offered by multi-adjustable Öhlins suspension, alloy rims, twin front discs, alloy yokes bars and tailor-made Arrow exhaust. During development the bike lost 39kg as the team removed everything not strictly needed for off-road riding and selected lightweight components wherever possible.
The bike’s moment of glory and a validation of the team’s work came when the Tramontana’s versatility ensured success at June’s Tridays Rumble. David said “I’ve won road races in the past, but nothing matches the feeling of being first past the chequered flag on the Tramontana. The perfect venue, full of passionate Triumph enthusiasts and the perfect bike for such a unique and special race. I just had to win!”
Öhlins fully adjustable twin shocks were specifically developed, increasing the front fork stroke from 120mm to 220mm and the rear wheel stroke from 106mm to 180mm. Rear suspension increased stroke was achieved by the addition of two solid alloy clamps that reposition the top of the RSU, also improving suspension progressiveness.
Replaced by lightweight aluminium spoke wheels from Excel in sizes 21″ x 2.5″ at the front and 17″ x 4.25″ at the rear. The 21″ front wheel was vital to achieve the right level of grip and control of the front end in off-road conditions.
The frame has been modified to reduce weight by eliminating all the non-essential features. The steel fork yokes have been replaced with aluminium parts.
Steel handlebars and risers were replaced with aluminium parts with Tommaselli grips and the footrests by modified bear trap billet machined Triumph genuine accessory footrests. Their position was changed to lower the rider in relation to the bike’s centre of gravity to improve standing-up bike control.
Front Brakes and Bodywork
Swopped for a twin 308mm disc system with two Nissin piston floating calipers, while the team also added a tailor-made side panel and rear mudguard.
Airbox replaced by inlet ports with individual air filters to improve low- and mid-range torque. Re-jetted Keihin carburettors. Eliminated secondary air system and tailor-made wiring harness. Ion-lithium battery.
