I also noticed this as it did sound cold from start. Monster sound without the dry clutch rattle.Poor bike he didn't let it warm at all before he took off! I'm old school but I let all my street bikes, dirt bikes, cars, etc. warm up from at least 30 seconds to a couple mins (depending on what they are and what they require the CRF250X takes like 5 mins!) before driving off. The bike really does sound just like the Monster 796 which is a good thing!
