IMPORTANT – READ BEFORE BUYING –   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.

 303 Performance Camshaft for select 1200cc water-cooled motors from 2019 onward. Pre Euro5 models only see below –

Made from CNC machined, heat treated and precision ground steel billet stock.

Fits Triumph T120, Speedmaster 1200, Bobber, Bobber Black, Thruxton R and S models only.

WILL NOT FIT SCRAMBLER 1200, SPEED TWIN, THRUXTON RS, TFC or later Thruxton models due to different fitting.

For use with standard ECU tune on Euro4 bikes.

Suitable for replacing the original camshaft in bikes using the (Triumph part number): T 1147525 camshaft.

In 2016  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 USA Emission laws, they decided not to offer the cam or de-cat exhaust for sale after the bikes were released.

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 and Torque right across the rev range, without need of any other modification to the motor.

Due to the larger valve overlap, our cam does not need the complicated exhaust valve lifter mech and this is not used just the OE chain sprocket required to be reused.

Just make sure the bike has a good battery fitted for cold cranking.

Basically a fast road cam, much more usable than a race cam. But as with most performance cams you may loose a very slight amount of power below 2500 RPM. However, it will have massive gains at higher RPM.

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

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.

Typical power gains in a stock bike are over 10+ BHP at rear wheel. Very slight reduction in torque below 2500 RPM (but not noticeable when riding) with very noticeable torque gains at all revs above 2500 to rev limit with a wide and flat the torque curve in mid range. More torque = improved acceleration and less gear changing.

Even more power will be available with an ECU remap as revs can safely be extended by 500 RPM and ignition advanced if you run super unleaded fuel. Further gains can be made if you improve the exhaust flow or remove the Cat.

On Speedmaster 1200 and Bobber models – to get the best results, you must use high flow air filters of pod type filters pod filters as the stock air-boxes on these models are too restrictive.

 I would suggest Installation  along side the workshop manual from Triumph or Haynes.
