TEC Performance Camshaft – 1200cc Motors Thruxton / Thruxton/ T120/ Bobber


TEC 303 Performance Camshaft for 1200cc water-cooled motors from 2016 onward.

Fits Triumph  Thruxton, Thruxton R, Bobber, T120.

Will NOT fit Thruxton TFC or Thruxton RS.  Due to higher compression ratio on these models.

Suitable for replacing the original camshaft in bikes using the (Triumph part number) T1147025 camshaft.

When Triumph originally announced the 1200cc bikes and accessory range they listed a performance camshaft and de-cat exhaust (Camshaft part number A9610492).  However, likely due to changes in Emission laws, they decided not to offer the cam or de-cat exhaust for sale.

We decided to develop our own cam for the 1200cc bikes based on that performance camshaft concept. Our 303 cam has more lift, duration and overlap than the standard cam and is designed to give a good spread of power right across the rev range.

The lack of overlap on all Euro 4 cams is one of the biggest areas that can easily be improved on.


Obviously we can only sell this camshaft for off road and closed circuit competition use. The use is entirely at the discretion of the owner.

Can be used as a stand alone modification with no other changes.  Just bolt in and go (just like Triumph designed it to be).  Can also be used with exhaust, air box and other changes for further gains in performance.

For example with only the camshaft and no other performance modifications on a 1200 Thruxton, we saw an instant power gain to 103 BHP (104.5 PS) and 83 Ft Lb of torque at the rear wheel.  See below Dyno graphs.

With a de-cat exhaust fitted (see Dyno below) this went up to 107 BHP (108.5 PS) and 84Ft Lb at the rear wheel.

All runs with standard ECU tune (latest anti-stall Triumph dealer map).  All runs were performed on the same dyno using same grade of super unleaded fuel.

Further gains can be made if you want to add a power commander and air box mods.

The video is a guide only and I would suggest using it along side the workshop manual from Triumph or Haynes.

Transformational Upgrade (Bonneville Bobber)

I paired the TEC performance cam with an airbox delete (BAAK Motorcycles),Slash TT exhausts (Triumph Performance Parts) and a boosterplug (to side step the Euro emissions standard lean fuel mixture at low revs). The power delivery is so much smoother and the sound 😍. I found the TEC instructional video extremely helpful and wouldn't hesitate to recommend this product.

Instant improvement

Had this cam fitted recently and a huge improvement over stock - bike revs and engine picks up much quicker, faster and lighter throttle response and of course greater acceleration and much much more fun to ride - de-cat and performance pipes fitted along with snorkel removal, PowerCommander and air filter and tbh the bike reminds me of a trail bike pick up and acceleration rather than the more gentlemanly ride style with the original camshaft. Fitting video superb and really cannot recommend this upgrade highly enough - huge grin factor and not that I'm bothered but better MPG( often ride with brother on a T120 with standard cam and same other mods so genuine comparison) perhaps because 6th gear is more useable and can be used much earlier and other gears engaged sooner and will still pull hard so if I do enough miles it might even help pay for the upgrade! Thank you TEC for taking the trouble to produce. 10/10.
