So they sit outside of your house for 10 hours on full throttle then do they?

If they did that, then you would be quite within your rights to go and smack them in the mouth.

As far as I am concerned, as long as someone is sensible (like me), there is nothing wrong with loud pipes. I certainly do not scream along in residential areas, I am in the highest gear possible without loading the engine (except for the whitehouse road bridges sixy).

Is a motorcycle with a load exhaust as instrusive as all of the chavved up boy racer cars with chimneys hanging out the back complete with 1kw of stereo? I think not. You hear one or two perhaps irresponsible bikers and label everyone else.

True, but your point there is?

Part of the attraction ole chap. Doesnt mean you will be even slightly touching the performance of such a machine, and you may want to be as safe as possible for the other 99% of the time when the brain ISNT disengaged!

Well, a lot of that is pub bullshit really. I bought my cans because I like the sound of a v-twin, and the believe that it makes you more noticable to other road users. I have just re-fitted the baffles, so I will let you know in a week if there is any noticable difference in other road users behaviour.

Hey blademan - you ever been to Stoke on Trent? There's a tunnel/bridge thing on the A500 thats about 3 times as long as Whitehouse Bridge...


Adam. If you run ANY engine with the exhaust system removed you WILL hole the pistons as it will run WAY to lean. Fitting a loud can isn't just as simple as unbolting the old one and bolting the new one one. The carbs have to be rejetted and proplerly set up in order to get the motor to run properly.

As for boys with toys?! Excuse me? Or is there something you know about me that I don't?

I'll have you know that my bike does not sound like an angry hornet stuck in a megaphone. Its a large bore (840) twin and it sounds glorious. It revs to about 7k tops.

Is that so? The reason I ask is because the combines I used to drive had no silencer and the exhaust system was all of 24 iches long. This was on engines at the highest power rating for that size and ran all day long at full throttle and the good operators could hold them at over 85% load all (14+hr) day. Some markets these machines were sold into called for silencers, most didn't. also many naturally aspirated tractors got turbos in the late 80's early 90's and ran straight through pipes with no ill effects.

I do like the sound bikes with noisey cans, but there are a lot of tossers that think that everybody likes to hear their bike for miles around, when they don't. I think everyone should listen to my CD's with the system turned up to 35, which is not what my neighbours suggested when they moved in last year.

Most bike accidents are people missjudging corners and ploughing into the hedge (Simon Wier in Bike). Not sure if a Micron end can will stop this happening. Not sure if a noisey pipe on my scooter will stop people overtaking me/ generally being a pain while I'm turning right into the yard at work either.

In my opinion motorcycles with loud pipes are more intrusive than cars with loud pipes, generally because of the higher RPMs involved and the fact the whole engine is acoustically exposed! I've heard a few really bad Subarus with dustbin exhausts which are loud but _nowhere_ near as loud as the guy down the road with the TL1000 with two Devil race cans on.

Yes you read it here first.

This evening as I was leaving the Reading vs Man Utd game on my WOLF can equipped Honda VFR V4 I was filtering out thorugh the usual insane A33 traffic.

a pair of fans leaving the match start to walk out between the stationary vehicles just infront of me and jump back just in time, a clear example of loud pipes saving lives.

LOUD Pipes May annoy, they may be illegal but in the battle for survival they are a vital weapon against dozy pedestrians.

(note Reading held out for a magnificant 1-1 draw in what was probably the biggest game in their history)

This difference of opinion is widespread, which is exactly why I'm calling for proper science (ideally a large scale study) so that we can drill down past experience and anecdotes to find the statistical facts.

Really? So will you be happy if forthcoming euro regulations lead to a 10% increase in motorcycle deaths?

And how can you possibly know that it won't?

I have already in this thread outlined a study format that has a very fair chance of determining the truth.

Though not exactly a Bike topic. I believe one of the big concerns about *fast* EV's is that they are nearly silent compared to ICE vehicles and that this could present a significant hazard to pedestrians and cyclists (and other motorists too! )

I have even seen it sugested that EV's should be made to generate an audible "Running noise" to overcome this!

I can only presume that you live in some quiet backwater and never go to London or other large metropolis. If you are filtering in the city a loud exhaust is a big advantage, so much so that the Met police never go after bikes for this at commuting time.

Don't get me wrong I understand that the "noise" on biking routes is sometimes invasive, I live adjacant to one of the best biking roads in the south of England and bikes are on there all weekend through the summer.

Having said that we also have Chinhook helicopters rattling our tiles throughout the day from the nearby Odiham and Planes that have not got to altitude. Add that to the three local recreational airfieds and powered parasailers that now use the common down the road. Where does the "quest" for a totally silent life in the country have to go? the only thing that will satisfy people is a total lack of use of the countryside, that is the end game planned by the land owners who supported the NERC bill.

As for all the how do you know questions, well its based on several hundred thousand personal motorcycling miles, with legal and illegal exhausts.

I support the Safespeed call for a study. it would be easy enough to do especially in citys where when a motorcycle pedestrian accident occurs the legality of the exhaust could be noted.

Please do not misunderstand me a bikers best line of defence is himself and I qould question any safety benefits with regard to other motorists but until we have laws that prevent jaywalking in place pedestrians are one of the biggest risks to a biker in cities and my personal experience supports loud pipes for that reason.

Something doesn't quite sit right here!

Known variables

1. Football match
2. Lots of people about
3. Lots of likely "worse for wear" people about
4. Snarled traffic
5. Pedestrians crossing between cars
6. Failing daylight coupled with lots of brakelights / headlights

Now I personally wouldn't have said that would present the best choice of environment to filter a motorcycle through, especially if your view of known and potential hazards in that environment is virtually zero. You stated that they jumped back, which suggests you were travelling at an inappopriate speed for the conditions in the first place.

Adam L raised an interesting point - there is a perception that if you ride a powerful motorcycle and have an accident its your fault...

have an accident skiing and its tough luck, fall off your horse and it tough luck, fall of your bicycle and its tough luck fall off your motorcyle and its your own stupid fault?

Adam L - worth noting that the <125s are over represented in casualty stats far more than >500cc bikes.

Imagine how people would have reacted to the power of top end mondeo 20 years ago. "how can anyone want a car that does more than double the speed limit and 0-60 in 7 seconds. Given the avg car was looking at a top end of 100 and 0-60 in 14 secs.

modern day litre class sports bikes are more forgiving with their 1bhp/kg than mid-80s bikes that had half the power.

Are you saying that given those conditions you wouldn't have filtered? I bet you would. Then comes the question of what is the safe speed, well in all fairness to your motives for the question I'll add that I am perfectly happy with the choice of speed thanks very much.

I am also perfectly happy with my personal choice to use a loud can, in a little over two hundred thousand miles over the last 5 years I have never had a tug from the BiB for the cans.
