aftermarket pipe, Lams allowed or not

[jellywrestler]

Simple question, if a bike has an aftermarket muffler is it still a lams approved bike?

My understanding is on a 250 its no issue but is on bigger bikes as it changes the power to weight ratio.

In saying that I have never heard of anybody having an issue with it.

It's not exactly clear about specific mods but any modification that increases or decreases power-to-weight makes it prohibited;

If you modify your motorcycle, it may not be approved

Any motorcycle modified in a way that increases or decreases its power-to-weight ratio is no longer LAMS-compliant, regardless of whether it appears on the list.

If you are a rider on a learner or restricted motorcycle licence, it is your responsibility to ensure you are riding a LAMS-approved motorcycle, as produced by the manufacturer. If in doubt, seek confirmation from the manufacturer's agent or dealership. If you are unsure who to contact, details for all major motorcycle importers are available on the Motor Industry Association website (external link) .

If you don't follow these rules you may end up with fines and demerit points.

I have wondered about this as well. Mine is bigger engine, and I would like to get better sounding pipes. However, I am not taking any chances as yet. Although I do question how much extra power can there be with just pipes, and no change to intake and tune.

I would think most cops wouldn't care, unless you fail the attitude test. However your insurance company, which lets face it are always looking for a way to reduce their exposure, may see it as a reason to not pay out.

Many take this to mean all changes to just increase horsepower is not permitted. But installing any lighter aftermarket parts ... effectively changes the Power to weight ratio The same horsepower but then it is a lighter bike.

Cops I worry the least about. It's the insurance policy I don't mess around with.

Yes, insurance is the main worry.

I did a silver ride forever course a few months ago and the instructor didn't give two f***s about a couple of learners on their 300s with slip ons.

1. They are not Police.

2. They are not Insurance Company rep's.

All they require is the motorcycles have current Registration and Warrant of Fitness labels displayed. And the riders are licensed to ride the motorcycle they bring.

Regardless of why they stopped you ... it's the attitude test that usually decides the result of the stop.

No doubt I don't disagree with that.

Though if a learner or restricted were to turn up to his or her CBTA assessment, the same instructor that didn't give two f***s would be well within his rights to not proceed with the test as the bike is not technically LAMS compliant.
