Triumph Bonneville Bobber! MOTONE Finally drops the H BOMB! Full Hpipe CAT delete Exhaust system! 

Personally I would recommend keeping removed systems in storage, They're already expensive and they may be worth their weight in gold someday. They don't currently test emission systems on bikes where I live, but they do on cars, and managed to make it retroactive.

Yeah, they are a pain!

Weight low and under the engine is optimal as well I believe

Same question as you Ian; I've got a speedmaster & would also like to know does this fit ok?

Yes it fits speedmaster but be advised no one is mentioning that after opening up the exhaust you will have to reflash tune your ecu which is another $500 dollars If you don't your bike will have deceleration popping every time you reduce throttle. It's quite annoying.

So no tune required?

well, that would depend on which country you live!

@@stuartfillingham Hi Uncle Stew, how long do you think it will be before they add exhaust noise/type to the MOT test.

@@daviddanielstephenson2833 Not long, removing freedoms and crushing small business is the norm now.

@@OurAmazingSkies Where we live in the remote Dales folks are already coming together for a common need, the paralell society is alive and well, it is much better in the rural areas for sure.

@@OurAmazingSkies Maybe we might support the little people Doug so they can continue to survive and even grow during the drought we see developing.

Not the case with the bobber model. Stop taking advice from Triumph groups on FaceBook.

@@stuartfillingham hmm. That’s what the sales manager told me at the triumph dealer. Edit: just took him for his word until this exchange. Just looked and what do you know. No welds.

@@UncleBogator Never ever takes advice from a salesperson, He was probably selling fords 6 months ago and has zero mechanical knowledge of any of the products he sells!

I just take it in, and they test it! Emissions are not tested.

Motone makes this system for the Speed Twin 1200 as well.

yes, I did mention them!

Maybe, but the fact the cat-box can be unbolted from the exhaust system might suggest it was intended to be removable by inquisitive owners. Contrast this with post 2015 Harley Davidson machines: The catalytic converters are either inside the silences (and therefore small and restrictive) or inside a box that is an integral part of the fully welded exhaust system. In order to remove them, you have to cut a window into the box, grind out the catalytic matrix, then weld the window closed again - far more difficult and time consuming. I wonder what the Triumph would sound like if the cat-box was replaced with a simple H-pipe?

What is the problem with a tail tidy ?

Emissions testing on a motorcycle? Not a legal requirement!

@@stuartfillingham Many thanks Stu - I'm learning ! Hope to rejoin the community one day

@@stuartfillingham "Not a legal requirement", yet....

@@stuartfillingham Yet.

@@jamesharvey44 You can say that about anything.

Is it not the case that in Germany no replacement part for a motor vehicle is allowed unless it has been certified under the relevant approval scheme, either the EU Type Approval scheme or the German domestic scheme? The two relevant directives will be emissions and noise. In the UK, whilst it is illegal for certain products to be sold unless they are approved and carry a homologation mark (e.g. tyres), there is no legal requirement for a replacement motorcycle exhaust to be certified. As the fuelling map is not altered the fuelling will still be set to run stoichiometric (which is actually only needed for a three-way catalyst) and with the lambda sensor still in place there should be no excess CO or HC WRT the limits for an MOT test, which are only at idle. Obviously they will be higher than if the catalyst was there but also remember that the three way catalyst is especially for removal of NOx and AFAIK that is not measured on an MoT test. So if no homologation is required and the emissions at idle do not exceed the limit for the MoT, that just leaves the noise. I had a look online and I found this nonsense: www.gov.uk/guidance/mot-inspection-manual-for-motorcycles/8-exhaust-noise So, take the bike to an MoT with a deaf tester and you'll be just fine. Joking aside you might want to ask the tester first if he or she is OK with it because these days MoT failures are recorded, aren't they? Maybe you don't want a prospective future buyer of the bike to be able to look up that it has at one time or another failed the MoT due to the exhaust noise?
