TEC 303 X Performance Camshaft for select 1200cc water-cooled motors from 2019 onward.

UK made from heat treated Steel billet stock.

Fits Triumph Speed Twin, Scrambler 1200 XC/XE, Speedmaster, Bobber Black

Triumph have changed the cam and part number in the above bikes and it is slightly different to the cam fitted in the other early 1200cc engines in the T120, Bobber, Thruxton and Thruxton R 1200cc models.

It looks like they will be phasing in this cam for all 1200cc bikes eventually except the TFC special models. So due to customer demand we have made a version of our performance cam to fit these models called the TEC303 X.

 

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. Basically a fast road cam, much more usable than a race cam.

The lack of exhaust lift and 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.

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 ( see how wide and flat the torque curve is ) More torque = improved acceleration and less gear changing.

Click here for Dyno Runs

Please see before and after dyno maps on a stock 1200 scrambler.  Both the before and after runs have full standard exhaust with cat and both runs are with standard pump unleaded fuel.

The only none standard parts on both runs are DNA air filter and Boosterplug.  ECU was on factory standard mapping. With the BoosterPlug fitted air/fuel ratio was fine.

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 and Bobber models – to get the best results, we highly recommend using pod filters or similar as the stock air-boxes on these models are too restrictive.

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

TEC Cam 1200 Speed Twin

Just adding a wholehearted endorsement for this cam. I installed it 40,000km ago and it has been absolutely great. Reasonably easy to install following video instructions and performance gains excellent. Together with intake and exhaust mods (snorkel removed, K+N air filter, decat, open V+H pipes) + a dyno tune (PCV), RWHP up from 84 to 98 with no noticeable losses in low/mid range. Makes the Speed Twin everything it should be :-) Highly recommend.

Tec kamaxel Scrambler 1200

Inkörning ca: 50 mil, så jag har inte testat prestandan än.
Dessutom måste jag skaffa nytt startbatteri. Ingen dekompressions ventil på nya kamaxeln.

1200 twin cam shaft, Speed Twin

Have the Tec cam in my Street Twin 900 and was very happy with it so also fitted the Tec cam into my Speed Twin 1200 and am also very happy with it. Performance improved across the RPM range with the bike now pulling from just under 2K RPM and stronger all through the mid range and higher RPMs although i do not spend much time above 5.5 - 6K as there simply isn't the need. The bike pulls so strongly from 2.5 - 5.5 that is where most of my riding is done as the pull out of corners is plenty. Also fitted k&N type air filters and have custom header pipes with the cross over near the radiator removed and a full size cross over fitted approximately where the cat would normally be. So with the Tec cam the bike can breathe properly and really opens the potential of the engine up. Pipes are Predator Pros from British Custom. Currently running T120 gearing although a tiny bit too tall is far better than the OEM Speed Twin gearing which is just too low for an engine with that much power (compared to the T120).
Highly recommended performance modification.

Fork springs

The progressive fork springs are a worthwhile improvement over the single rate units, especially if the preload adjusters are added also. You end up with a much plusher ride and you don't feel every bump in the road.
I can can recommend them.
