TEC Performance Camshaft – Royal Enfield Himalayan 410cc

£199.99

First announced in June 2020 – We have known for a while how to unleash more power from this 410cc motor.  Due to obvious global circumstances this part saw some delays but has now been fully tested and is ready to go.

Made in the UK from scratch with a single piece of machined billet steel before being heat treated for hardness.

Elsewhere you will find that competitors have just ground the base circle on the stock Himalayan camshaft.  However, we found that this restricted the way the timing and lift could be changed.  Lift on a re-ground stock cam is also restricted by the tappet adjustment range to about 0.5 Millimetre in lift.  Modifying a stock cam also means the exhaust valve lifter arm needs to be ground very thin.

So, you can see why we started with a fresh blank steel billet and developed this drop-in Camshaft. This also means the problematic exhaust valve lifter mechanism is no longer needed due to the Camshaft timing and valve overlap.

Tested extensively on all Euro 4 and 5 models during summer and winter temperatures.

Easily fitted by amateur mechanics (see our detailed video below) and even without any other changes to the ECU this will give around 20% extra power. Detailed written instructions with diagrams included with the part.

Please see the Dyno sheets on our 2019 stock Euro 4 Himalayan with standard ECU, more power can be gained with other simple changes if you wanted to go further.

The 3 Dyno runs are:

1) Bottom line – stock Euro 4 Himalayan
2) Centre line – Same bike with just the new camshaft installed, no other changes
3) Top line – Same bike with camshaft and DNA air filter and free flow silencer installed

One big advantage is that the bike now has the power to pull an extra tooth on the front sprocket which gives higher cruising speeds at lower revs with the added bonus of improved MPG.

This camshaft will completely transform your bike! Runs smoother with no more struggling to over-take 56 MPH lorries!

Cost effective and worthwhile

I had a local garage fit the the camshaft, and I while I wouldn't say that the bike has been transformed I am very happy with the result. The engine is now much willing and lively, and there's no need to work the gears anymore to overtake. Riding on faster roads is more enjoyable and relaxing because of the enhanced power. Fitting one of these cams is a cost effective and worthwhile improvement to the Himalayan.

TEC Camshaft

Just run in for 300 miles today , gave it some beans and very very happy, has K&N filter, home made air filter over and Lextech with baffle in. Basically starts better, and feels like it has a lot more oomph at higher revs, pulls really well from 4000 rpm up to limiter. Stuck with standard sprockets for now but might go up one on front, definitely worth the money and the wait, cheers TEC chaps ,

Dyno Results prove this cam is the Best available now.

So it would seem, Tec Cam is the Red Line from my previous Run(back to back), Blue is the first cam to hit the Market :)
AFR looks boring but The HP and Torque which are Rear Wheel Figures not at the cranc, show 31RWHP and 30FtLb Torque, as opposed to, well look at it.

Just to make this clear for everyone that this dyno run was done on a bike with 477cc kit
