HP differance

Anyone notice the HP & FT differance in The Bobber and the Truxton.
Bobber 77hp & 78.2 ft

Truxton 97hp & 82.6 ft

I wonder what it would take to boost up Numbers on the Bobber to match the Truxton....?

New cams + mapping ?
Though TEC have now officially stopped production of their aftermarket Cams for the Bobber:


Development on water-cooled Triumph cams cancelled

We have decided to stop all development and production on our water-cooled Triumph cams
Firstly, we would like to say thanks to everyone for being so patien regarding news on the cams we were hoping to produce. A lot of you have been excitedly waiting for any further news about them so that makes it all the harder for us to have to say that we have decided to finish all development on them. We are sorry that it has ended up with this situation but we will explain briefly why we have done so and hopefully you will understand how we have reached this difficult decision.

In 2017 we had figured out the restricting factor on the new Triumph models and were working behind the scenes to bring a product to market that would bypass this and unleash the true potential of these bikes. We put a video up on our YouTube channel explaining this and our plans for a new camshaft. We were recommended to use a well-known UK cam manufacturer and initially placed an order for 100 cams.

We had been promised that the work would only take 6 weeks so went ahead and began planning for thorough testing of the part and quality control regime for the part. We gave our customers a release date that was generous in comparison to what we had been quoted for the production time. Unfortunately these dates were missed on production repeatedly and we had to keep pushing things back. When we got the final sample of the cam that was to be released there were a number of manufacturing errors on the cam that meant it was impossible to fit.

This meant they had to be returned and we were set back another few weeks. We eventually got the adjusted cams back but once we tried to fit them we found there were still a number of errors with the cams. This meant that they did not pass our quality control and may have caused damage to engines.

With a part that needs to be so precisely engineered we were no longer happy to proceed with this manufacturer as we had lost confidence in them producing an accurate enough part. We would never want to sell something to our customers that we knew could jeopardise their bikes and potentially cause thousands of pounds in damage.

We have been unable to get realistic quotes from other UK cam manufacturers. We are reluctant to use a overseas manufacturer considering the issues we have had so far. We have racked our brains but cannot see a way to make it work. Coupled with the fact that we have not got a clear idea of how the cams will effect your warranties meant that we have decided that we are going to stop development of this part.

We were happy to release the information out into the public domain. We have put almost a years work into this project and have not ended it lightly and hope this information is of use to you.

Again, we are sorry that this is the outcome, we hate to disappoint our customers but hope you can see why we could not proceed with this project.

I am curious as to who the manufacturer is that was unable to produce a decent cam. Perhaps it explains why they were so much cheaper than the their rivals?!

My Blobber made close to 93rwhp with no new internal engine parts, (just headwork + usual bits) which is more than a stock Thruxton R.

Reprofiled camshaft took it to 107rwhp & 93ftlb, it outpulls my TTR now.

Stock cams in 1200's are all the same.
