Not to side rail this thread, but Gerhard, how old does a motorcycle have to be to be excluded from the new noise rules?
In some states here if the bike is older than say, 30 years, it's does not have to comply with current noise rules and can legally run just about any exhaust system without penalty.
Thanks.
Hi Dan,
that differs from year to year. Generally spoken, the older, the louder. It is correlated to the date and then valid regulations, when it got its first traffic allowance from the european authorities. Old Triumphs, Panheads, MV´s etc. can be operated really loud.
But: the biggest leap "into the silence" is happening right now, with the new restrictions for the oncoming 2017. We then will have here in Europe new, restrictive emission regulations, the so called "Euro6", that will castrate the pipes too. Just have a look at the J&H or V&H-websites for european customers - that´s why these enterprises developed this fancy electronically controlled exhaust-systems, to meet the new european test cycles. My FLHXSE has still the stock pipes, and if you open the throttle - they are really loud. Stock! I think this will differ a little next year. And maybe its getting worse (= even more silent). What is bad for new customers - cause a bike, especially a Harley - HAS to be heard ;-) and, well, better for people who are looking for a "new old" bike. For riding or tuning reasons.
And yes, you´re right, also in Europe the so called "Oldtimer-status" is from 30 years on. Then its gettin´ really loud ;-)))
regards, Gerhard.
