2015 Triumph Thunderbird Storm ABS

2015 Triumph Thunderbird Storm ABS

Less chrome, more power and more attitude. The Thunderbird Storm comes with a 1700cc engine and hard-edged style.

Based on our original Thunderbird, the Storm keeps the pure Triumph twinned headlights but adds a low, blacked out look that's mean and minimalist for massive street presence backed up by huge torque and confident handling.

We squeezed 102cc more from the muscle-bound parallel twin engine so that it packs an even bigger punch. Still laid-back but underpinned by serious power and the best handling in the class. This is a cruiser with a dark side.

• Performance

We took the 1597cc parallel twin from the Thunderbird and boosted its capacity to 1699cc with 3.3mm bigger pistons in huge, 107.1mm bores. So the Thunderbird Storm does have a classic-looking engine that packs a mighty punch, but that power is delivered smoothly thanks to twin balance shafts.

• Configuration

Despite the air-cooled appearance, the Thunderbird Storm engine is liquid-cooled. We placed its radiator unobtrusively between the frame downtubes and the fat, twin exhaust headers.

• Blacked out

The Thunderbird Storm has a big black engine with upright cylinders and machined cooling fin edges to help define its imposing shape.

• Belt Drive

The final drive is an inverted tooth belt with carbon fibre strands to give it a higher tensile strength than steel. While the pulleys have a patented ultra-hard coating that minimises wear so that the whole belt drive system needs very little attention. It's really quiet and clean too.

• 6 Speed Gear Box

The transmission uses a six-speed gearbox with a tall top ratio for relaxed highway cruising and exceptional fuel efficiency.

• Fuel efficiency

We gave the Thunderbird Storm double overhead camshafts and four valves per cylinder, along with a very tall top ratio in the six-speed transmission for a great ride and to help the fuel economy. Even at 75mph you get almost 50mpg, as good as some commuter bikes.

• Suspension

We gave the Thunderbird Storm fat 47mm diameter forks with plenty of travel at 120mm. And the rear shocks are adjustable for spring preload so you can set the bike up to suit your load or riding style.

• Handling

We used all of our engineering expertise in making the geometry just right, so the Thunderbird Storm steers as great as it looks. Even at low speeds.

• Brakes

We wanted plenty of stopping power to match the engine on the Thunderbird Storm. So you get a pair of four-piston callipers at the front to scrub off speed in an instant and give great feedback, backed up by ABS as standard.

• Riding Position

You get a feeling of control on the Thunderbird Storm, with forward-sited footrests and controls and wide, pulled-back bars for a spacious, comfortable riding position. Comfortable enough for much more than a quick trip into town or a Sunday spin.

• Wheels and tyres

We’ve fitted Metzeler tyres to five-spoke cast aluminium wheels that, not only look the part in their black finish, but are light for sharper handling.

• Frame

We built the twin spine, steel tube frame of the Thunderbird Storm to be exceptionally stiff. Then we reinforced it with the engine itself, making it a stressed component of the chassis for even more agility.

• Seat height

With a seat just 700mm from the ground, you’ll find the Thunderbird Storm very accessible for such a big bike.

• Tank range

Typical Triumph fuel efficiency and a 22 litre tank means you can cover more than 200 miles between refills. Not bad for any bike, let alone a cruiser.
