Camshaft (de restrict) Street Scrambler 900cc water-cooled and later chassis number Street Twin/Cup/T100 up to 2019



Any doubts please contact us directly before purchasing.

TEC 202 CAM REPLACES TRIUMPH CAMSHAFT part NUMBER T1147042 ONLY (if in doubt check you bikes cam number).

Check your bikes VIN number and make a note of the final 6 digits.  If your final 6 digits are numerically HIGHER than the below numbers then the cam will fit.  CAMS WILL CHANGE AGAIN on 2019 (high power) bikes.


Street Scrambler – will fit all VIN numbers up to  914448  (revised 2019 model (hi output)) this bike uses a different cam

Water-cooled T100 – all VIN numbers after VIN 818590

Street Twin – all VIN numbers after VIN 818610 and up to 914448 (revised 2019 model (hi output)) this bike uses a different cam

Street Cup – all VIN numbers after VIN 818598

This cam has been designed by us to de-restrict the 900cc motor.  Made exclusively for TEC in the UK from CNC machined steel billet and fully heat treated for maximum durability. Fully covered by manufacturers backed 12 month warranty.

The cam is now perfectly matched to the motor for road use with no loss of bottom end torque and a progressive power curve with increased performance and still has the same MPG.

Your bike will still comply to euro 4 if no other changes are made and no remap of the ECU is required. This will upgrade your motor to 2019 spec bikes with a similar power output.

We do recommend that you check to see if you have the latest map update from Triumph on your bike as they run much better with this map – cam fitted or not.

Meets expectations

Quick shipment and very good packaging. Brought my street scrambler to a good mechanic for fitting, he states the job was pretty easy and all done in a 3-4 hours. Already had Vance & Hines pipe with de-cat, DNA filter and booster plug on before installing the camshaft so I cannot compare with100% stock bike.. however you can REALLY feel the difference.. no power loss at low rpm, and at higher rpm ranges it basically keep on pushing instead of dying! The spirit of this engine remains the same but the bike is faster. Normal daily riding to me was shifting from 1st to 5th gear reaching 110-120 km/h. Now it just go easy to 140-150 and you feel you could push more, but there’s no need actually 😎 consigliato!!

It works!

Older Street Scrambler used for B, C and unclassified roads, fitted aftermarket exhaust and free flowing air filter. After 2 days fitting (probably 1 combined) only problem being a mis-fitting rocker cover rubber seal, soon fixed. Used the locking pin but not the camshaft locking tool. After 300 miles running-in, the bike feels livelier and 'right'. No longer breathless at Motorway speeds, roll on in top gear improved. Acceleration now 'entertaining' rather than 'pleasant'😊. Didn't want to trade for newer model, now I don't have to.

Do it!

I received my new camshaft the day after ordering and got to work following George's video and the Haynes manual. I also spoke with George at TEC parts who was super helpful. Fitting on my Street Twin took me most of the day because I was being I was being ultra meticulous, but was fairly straightforward. The cam needed to be run in for 100 miles - revs kept below 4000rpm and I took the bike for a long run to do it. Under 4000 revs performance was pretty similar to stock, but once I hit the 100 miles and began to push harder, the difference was obvious. I was always disappointed with the way my Street Twin power just dropped at higher revs like there's a rev limiter, but that has now gone, the engine is happy to be revved much higher and speed in every gear in increased. I also did a de-cat a couple of months ago

I haven't pushed the bike too hard yet, but on the motorway it didn't feel that the bike was underpowered as it certainly did before and I've got much more confidence it it's performance. This is a transformational upgrade in my opinion and I'm so, so happy with the bike.

My advice is to do the upgrade, you won't be disappointed!!

New camshaft

Before I fitted the new camshaft there is definitely something missing it worse lacking full power now it goes a lot better it doesn't feel like it's being held back I also brought a D N A air filter and that also makes it feel smoother I can't wait to try the slip-on exhausts when they come in stock


It’s too fast!!! And I love it!! It revs really well and you got more hp. Best upgrade ever. Thanks!

Guys! Get them for your bike.
