Shhhhhhhhhhh

3000 or 4000 revs was the range specified in the last lot of regs, interesting tho as my VFR is just ticking over at 3000 revs yet my Volkswagen redlines at 4000! hardly fair for the ol' volksie at the top of its rev range.
Doubt, even with its stock spec exhaust, it would pass the test anyway even with the current extra allowance for rear engined vehicles...

Must dig that out of my stacks of paper because I can't find it on the net now. When I read it it had an implementation date and was supposed to be all set to go. maybe what we are getting now is a modified, delayed version of it?!?

Why do they never specify the rev range tested?

My bike is quite quiet at up to 3,000rpm....it only sounds visceral at about 6,500rpm onwards.

They do. 50% of peak power revs.

There's a bunch of (not very reaosnable) defaults in the cae that peak revs are not known.

There's a fall back 'common sense' provision to deal with something like a vintage vehicle .
