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

IMPORTANT – READ BEFORE BUYING – This product is not USA 50 state compatible and cannot be used in the state of California.  The product is strictly for off-road/race/demonstration use only.  It is not road legal for emissions in the EU or the UK.  It is the customers responsibility to use this item responsibly to comply with local laws.  These parts are not BS-marked, E-marked or TUV-approved.

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.

Disclaimer-

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.
