Modified LAMs bikes?

[george formby]

This needs NO explanation at all if you simply read what is written:

Is your motorcycle 250cc or less? Yes - is it on the banned list? Yes = not LAMS
Is your motorcycle 250cc or less? Yes - is it on the banned list? No = LAMS standard or modified
Is your motorcycle 251cc or more? No - then see above
Is your motorcycle 251ccor more? Yes - is it on the approved list? Yes - is it standard? Yes = LAMS
Is your motorcycle 251cc or more? Yes - is it on the approved list? Yes - is it standard? No = not LAMS
Is your motorcycle 251cc or more? Yes - is it on the approved list? No = not LAMS

The process is really simple so if your RD is 250cc or less then it can be as highly altered as you like provided it is not on the banned list and from memory the RD is not mentioned as it is too old.

Hope this helps

You're a bad man. Got my eye on a nice fat spannie t'other day which would do wonders for Rossi's bike.

When I changed to a replacement pipe that was noisier than the original I just pushed some steel wool down it when getting a warrant but it does blow out after a while.

Do a little experiment with some steel wool and a cigarette lighter.

Now ask yourself 'why the fuck would anyone ever stick that down an exhaust system'?

Then ask your friend rastuscat if it is any fun watching your bike being incinerated.

I'm liking that warrent tip

I wouldn't...

Just understand ... when YOU take your bike in to get a WOF ... it is the bike getting tested ... NOT you.

The testing establishments have THEIR requirements for WOF. No allowance is made for the registered owner to be unlicensed to ride it legally on the road. The key words are ... fitted ... to improve the power to weight ratio. If it is not fitted for that purpose (On some older bikes, original pipes are hard to get and expensive) ... or fails to improve the power to weight ratio ... it should be deemed legal.

[FJRider]

The way I read it is that modifications are allowed for bikes 250cc or less, the no mod rule only applies for bikes between 251 and 660cc's.

You read correctly ...

[FJRider]

Ok, so it seems this is a bit of a grey area really. I'm still under the impression that any mod that increases the power to weight ratio is not allowed, regardless of engine capacity. But looks like I'll be fine unless I really piss someone off, or get pulled over by a cop who's having a shitty day...

There is no grey area. OVER 251 cc No modifications to increase the power to weight ratio are allowed.

End of story.

Cool, my DR600/GN250 is LAMS legal then

Quit worrying about it and just enjoy riding it.

Steelo pads crate awesome spark clouds at high speed.

From experience, it's heart stopping watching a bike go up in flames.

I can imagine - I watched my parents car burn once (something in the rear differential failed, it drained itself of oil and shit caught on fire ) Damn that was a sight and a half. On a rural road too. Closest house was quite a walk away. By the time the fire brigade got there it was a fire ball. Never blew up though (props to the fire men who jimmied open the fuel tank of the flaming wreck and filled it with that foam stuff)

It is a very vague law

If i remove the heavy factory rear rack rear footpegs and factory tool kit from my 650 its power to weight changes and so its not LAMS

If i install a hidden booster chip or tweak the ecu its invisible but ups the power to weight ratio and noone will ever know

If i put a 740cc bigbore kit in it noone would ever know from the outside

Exhaust seems too easy for cops to pick on if its too loud and does not have factory markings on it

Probably the only time the bike would get a check to see if its LAMS compliant is if you use it for a practical license test L to restricted or restricted to full

Warrant check does not care if its LAMS or not as long as its not too loud dangerous or obviously highly modified

[R650R]

I am SOOOOO going to shove some steel wool up my exhaust pipe, sounds awesome fun... expect it to be as good as the time I made some lightweight homemade magnesium brake pads...

As others said it only needs to be LAMS when learner riding it, or crashing as the case might be, nothing to do with WOF guys.
If you do come to greif I'd make the cops try and prove its not LAMS condition, be too much paperwork and you'd prob just get speed ticket or whatever instead.
Below - NOT LAMS approved but rider is Full classes 1-6 rogerrrrrrr btw someone mentioned noise, the limit is way high for bikes, not to be worried about unless you have a modded Harley etc...

It is not vague at all, it is pretty simple! But the truth of the matter is, if your bike is on the approved LAMS list very few cops will care or even look to see if you have modified it in a way that makes in non LAMS compliant.

Can you get new chambers for a rd250 these days that aren't "modified"? I think that's an argument in itself.

Does it qualify for classic status yet?

The simple answer is, the RD250 (air cooled) were NEVER manufactured with expansion chambers.... the 250LC was Yam's first 'factory expansion' The Suzuki X7 was the other 'factory expansion' OEM exhaust pipe.Possibly the younger Popo of today would not realise this, but I am sure there are plenty of 40+ popo out there who DO know the difference...
If the pipes are really loud, you could ge a pair of 'stingers' made and welded on, to reduce the crackle somewhat.
