Question for other bikers,

Google could not provide the answer, does anyone know if fuel management systems (example Dynojet, V&H fuel pack, etc) are allowed. I am looking to put a K&N filter on the bike and upgrade exhaust next year. If not, is there anywhere near Basel that I can go to for a dyno tuning?

Thank you

See ASA Guideline 2b Chapter 4.8 https://asa.ch/it/biblioteca-online/direttive/

In general anything which may change noise, power, and exhaust emmision needs approval and you must show that you are still within the limits set by the law relevant for your vehicle.

In conclussion with the right papers you can do chiptuning and use power comander, dyno jet etc. If the right papers are available is another question.
Static chip tuning should be easy, adjustable and dynamic stuff such ans power commander, dyno jet etc. is most likely out of scope.

If you simply replace your existing foam or paper filter in the airbox with a K&N then I do not see any issue. If you remove the airbox and put a "mushroom" filter at the inlet of the throttle valve body/carburator then you most likely must show and proof that you are still witihn the limits.

PS: It is your duty to show that your bike is compliant in case it has such modifications. It is not their duty to show that it is non compliant. It is by default non compliant until proofed otherwise.

Depending on the type/popularity of the bike this may be easier. My chats in relation to HD bikes is that a remapped chip is the way to go although the paperwork can be painful.
For exhausts most larger manufacturers provide paperwork to go with them. I'll need to double check with a friend but I believe the university does gas and dyno testing. Double checking required due to a mildly beer blurred conversation.

Bottom line is that any non-original part fitted needs to have CE approval. Most aftermarket exhausts designed to help performance will not have this, nor will K&Ns, mapping kits or add-on or replacement chips.

So the way to go, if you really want to do it, is first to accept that you're not going to be strictly legal. Yes, this is the reality and it's up to you to decide if you want to do it or not.

If you're happy to do that then you need to ensure that there's nothing noteworthy to the eye or ear about anything fitted and hope that you don't get pulled over by the one cop in 500 who might know enough to spot your changes. For the MFK, of course, you'd need to refit original parts if they would be spotted - the exhaust is the most obvious one - for the test, as long as it rund OK for a short test drive, and then refit afterwards.

Illegal it may be (it is) but this is why you won't notice many modified cars or motorbikes in Switzerland. They do exist, in relatively small numbers, but are designed not to attract attention, which of course for many people defeats the object entirely, given that it's often about being seen to have something special, whereas if you wanted a proper fast bike you'd just buy something better in the first place and leave it standard.

Thank you all for your answers. This is exactly what I was looking for.

I ride an Indian Scout and I like performance, but I'm not looking to be a street-Rossi. I just want to change the exhaust note (I don't want it louder, just deeper) and improve the throttle response in the low end. The bike performs great and sounds good above 4k, but has a high pitch below that.

I know I can go with the V-Performance or J&H systems and get the paperwork, but the J&H is too loud in my opinion and I don't like the idea of paying 1,700 CHF for the v-performance.

Well I'm no street Rossi either, the only time I get my knee down is when I'm cleaning hard to reach places.

Swiss moto is 3 months and there are a load of dealers flogging pipes there. That said they are not all the friendliest and try to spend a disproportionate amount of time trying to look pissed off. Maybe it's because I was asking them questions...

Has a ride been organised for members here? I see a fair few bikers in the forum?

I'd be up for a group ride
