Newly-revealed specifications for the 2016 Triumph Thruxton and Thruxton R show that the ‘High Power’ version of the firm’s new parallel twin engine manages 97PS compared to just 80PS for the Bonneville T120.
The figures reveal that the Thruxton’s peak comes at 6750rpm, just 200rpm higher than the T120’s. Confusingly, the ‘High Power’ engine also makes more torque than the ‘High Torque’ version used in the T120, with a peak of 112Nm compared to 105Nm. The Thruxton’s delivery is more rev-happy, though, with maximum torque at 4950rpm compared to just 3100rpm for the Bonneville T120.
In terms of economy, the more powerful Thruxton doesn’t lose out too much to the T120, at 61mpg (4.6l/100km) it’s just 2mpg less than its less powerful sister machine. CO2 emissions are fractionally higher at 106g/km.
The Thruxton’s chassis spec includes Kayaba 41mm forks and Kayaba rear shocks, adjustable only for preload. The Thruxton R, in contrast, gets Showa 43mm upside-down Big Piston forks with a full suite of adjustment allied to Ohlins rear shocks, again fully adjustable.
Both versions get a brace of 310mm front discs but the R features Brembo Monobloc calipers while the base model makes do with the same Nissin four-pots used on the T120.
With extra power to handle, the Thruxton’s tyres are bigger than the Bonneville’s, with 160/60 ZR17 rears and 120/70 ZR17 fronts. Again the R gets a higher specification, with Pirelli Diablo Rossa Corsa rubber as standard compared to the Thruxton’s Pirelli Angel GTs.
As with the rest of the range, buying the bike when it goes on sale at the end of April will be just the start. There’s a huge selection of options including a ‘track racer’ kit with a cockpit fairing and single seat cowl, lower bars and a Vance and Hines silencer. A similar café racer kit adds the same parts but without the low clip-ons and fairing.
