Scorpion exhaust - legal without baffle?

[mini-si]

hi all newbie here so please take it easy on me;). recently purchased a pointy 2004 sv650s, love the bike to bits and a massive step up from my aprilia rs125. The sv has k and n air filter,pc3 and scorpion exhaust which sounds the nuts. today discovered the exhaust has a removable baffle which gives a nice deep tone to that wonderful v-twin,BUT would it be road legal to have the baffle removed?kind regards and thanks in advance

[davepreston]

road legal, strickly NO, done on a regular basis by most people (not me of course your honnor) hell yeah, unscrew ,pop out and enjoy that growling v twin goodness

edit
your neigbours will hate you, you will scare old people and children walking down the road, you wont give a **** after 10 seconds of hearing it

fair warning served i belive

ive got a curvy with a unbaffled scorpion can :) its pretty loud but when at lowish revs through town i dont get many looks. depends on how hot the cops are on bikes in your area. where i am it doesnt seem to that bad. its justa case of luck really and not reving it all the time

plus if you did ever get pulled over all the cans are E marked so just dont say that there is a baffle. and it will be fine :)

Here we go again.

Please read the regulations for type approval. (http://www.vca.gov.uk/additional/files/vehicle-type-approval/vehicle-type-approval-for-motorcycles/vca039.pdf) Whilst VOSA does not enforce the regs through the MOT, They and the cops do and you are liable to be nicked for breaching the C&U requirement assuming the police officer knows his job.

The whole of Europe type approval for motorcycles does require any replacement exhuast system to be e marked or show the eec directive under which it was apporved for use.

Specifically for replacement exhausts
Exhausts - Replacement Silencer (any silencer not fitted to the vehicle when it was
originally manufactured). A replacement silencer for motorcycles and mopeds first used on or
after 1 January 1985 must be constructed so that if it was fitted to an unused machine of the
same model and date of first use, the machine would comply with the requirements of the
Directive or British Standard applicable at that date.
Silencers are also subject to a number of marking requirements. No machine used on the
road may be fitted with a silencer marked “Not For Road Use” or words to that effect.
Similarly, any silencer fitted to a machine first used after 1 January 1985 must be clearly and
indelibly marked as follows:
Date of first use Marking

I don't see the point tbh, I think it sounds a bit daft - something a sixteen-year-old would do to his RD50 to make it sound 'ace'!
Unbaffled exhausts just sound anoying and don't do much to give biking a good name imo.
Just try to remember how you feel when you see/hear a 'wide-boy' Saxo with an exhaust the size of a litter bin hanging under the rear bumber - sounds ridiculous...

I love the sound of mine with the baffle in. It's plenty plenty loud enough!

[barwel1992]

^ 2 above are obviously old codgers

and a saxo's are slow so should be quiet bikes are fast so should be loud just like sports/super cars are loud

[kwak zzr]

my yoshi sounds ACE unbaffled :) and seen as it has'nt got any markings on it i'll just play the "i didnt know" card :)

+ a squillion

I used to have a big exhaust on my 205 gti (the saxo of the 90s) and it sounded ace :D

Also loud cans save lives.

[Reeder]

Loud exhausts on cars, unless good cars, are stupid.
Loud exhausts without baffles in on motorbikes are awesome. It's just the way it is.

[daveb]

Loud exhausts sound good on a decent in-line 4 like an R1 or ZX6 etc. but the v-twin isn't the most appealing sound as it is and all the ones I've heard with no baffles just sound silly.

I'm 37 so yes, I would probably be classed as an old codger, but hey...!

Grow up ;)

Well thats all very much a matter of opinion isnt it. I love the V twin rumble, theres a guy in work with loud cans on his ZX6r and a few people have said that they prefer the sound of mine.

Agree on small/slow cars big cans look and sound silly, but on a quick car loud zorsts are fine by me.

[Dicky Ticker]

Just be hopeful that when and if you get stopped that the copper is an idiot.Should you get stopped by traffic police I can assure you they are not---so you decide.
Taking it you have stepped up after taking a test recently so do you want to have a retest if you get points accumulating for silly things such as your exhaust bringing attention to you.

All for a bit of noise!!!!!

[Timothy Quinn]

I have a Fuel with the baffle removed on my K5 and it sounds just so proper and I am 54 in May!
A vee twin needs to be heard and loudly at that !

[daveyrach]

I agree with both sides here, the V twin sound is nice, but i think with and unbaffled unrestricted exhaust it can sound too loud and very harsh. I have a baffled Motad Venom which is still loud but not in that harsh crackly way and people can hear me coming, make a very nice thundery rumble.

[STRAMASHER]

IL4 600's with noisy cans are all noise and not a lot of go. Around town they annoy me more cos they sound like you are riding like a **** (speed) cos you are having to use a zillion revs. Much more likely to get stopped by the cops. 400's are the worst, 2smokes not far behind.

Vtwins and litre+ 4's you only need to tickle the throttle. Sounds slower. So less conspicious. Less bother in my experience.

Speed guns or daft stubby pipes and your gubbed though.

Loud pipes save pedestrians lives at least.:)

eh =; "not alot of go"???? little gixer has plenty of go :)

[daveb]

"Well thats all very much a matter of opinion isnt it" - yep, it is :)

[daveb]

I guess my point is that a de-baffled exhaust sounds like your bike should be putting down twice the bhp it actually is hence: its a bit silly (like the Saxo analogy).

Maybe on an SV1000 but not a 70bhp 650...

Each to their own tho I guess

[STRAMASHER]

Yer right...:(



...on the cam ;)

Thing is the new ones rev that fast to get there, they sound like 400s used to. Screamin' demons past the house and your not even breaking the law (much/-ish)

Thought you had a SV thou'?

[madness]

Baffle or no baffle, E marked or not, if a replacement exhaust is louder than the manufacturer's original, it is technically illegal under 'construction and use' regulations. I doubt that most police persons are even aware of this fact, so you probably wouldn't get done.

If you prefer the sound with the baffle out, then run it that way.

[kwak zzr]

Thought you had a SV thou'?

na sold the sv1000 to pookie :)

ya ya right tho 3 digits in 2nd does sound like all hell is breaking loose! ;)

[a1istair]

My baffles fell out once - you could always try that excuse!

[tonyk]

Not too sure if it’s illegal, but as long as you don’t rev the nuts off when riding past police they won’t pull you over.
I never did find my baffle , must have got lost in the box that I brought it in, oh but I did find it when I sold my bike…..lol.... :smt037
