You’d think they’d put better silencers on bikes, but sadly it just does not happen. Trials bikes are quiet compared to other things, but even at our local trials comps the one or two 4Ts are normally the only thing you hear on the other side of a hill. I think it is more a sound frequency thing than an actual volume thing, but whatever it is the sound of your average 4T single carries for miles. Not a good thing for the times we live in. Personally these are all considerations when buying a bike. If a 4T was superior in every way i.e. lighter, better grip, harder to kill, cheaper, easier to ride, easier to maintain, etc… I’d probably get over that one aspect, but let’s face it for a bike that needs to be light/manoeuvrable and does not have to be high performance I’ll go with Less-is-more.
