Carrying the banner of the Bonneville’s racing heritage, Triumph looked to the Thruxton, appropriately taken from the 500-mile racing series that first helped garner the Bonnie’s racing cred. While, as with all the new Bonnevilles, the authentic appearance is important, the primary emphasis with the 2016 Triumph Thruxton and the R was on power and handling.
To take care of the power of the Thruxton, Triumph massaged the engine into what it calls the 1200cc “high power” state of tuning. While the 1200cc parallel-Twin maintains its same basic eight-valve configuration, the performance increase comes from the “low inertia” components, including a lighter crankshaft, higher compression head, high-flowing intake and exhaust, plus revised EFI tuning with sports mapping (in addition to the Rain, Road, and Sport ride modes). The resulting 82.6 lb-ft of torque at 4950 rpm is a whopping 62% more torque than on the previous Thruxton. Also, note the higher rpm of the torque peak which points to the revvier nature of the engine. This type of jump in power would be difficult to achieve without the upgrade to liquid-cooling.
The Thruxton R adds a Showa fork, Brembo brakes, and Öhlins shocks for the ultimate in Bonneville-based performance.
While the information on how Triumph sharpened the handling of the Thruxton is scarce, we know, thanks to information from the chief engineer, that the Thruxton and the R have significantly steeper sub-23° rake. Also, one of the few specifications revealed at the unveiling is that both front and rear wheels will be 17-in. spoked units wearing Pirelli Diablo Rosso Corsa skins.
Suspension and brake components separate the Thruxton from the Thruxton R. While the Thruxton appears to use twin shocks with ramped preload adjusters and the same dual-disc, two-piston calipers on the front wheel, the R model gets some of that ever-so-sexy gold …read more
