My curiosity got the best of me, so I weighed all of my stuff with a single bathroom scale, one wheel at a time.
2005 Beta Rev 250 = 164 lbs (a splash of gas, not that it really matters since it holds less than a gallon anyway)
2003 Honda CRF230 = 242 lbs (.5 gal gas, barkbusters)
2008 KTM 450 EXC = 255 lbs (.5 gal gas, barkbusters, disk guards,
removal of emissions crap, mirrors, stock turnsignals, switchgear and rear fender assembly, replaced with lighter stuff, no skidplate)
1978 Husky CR250 = 214 lbs
Considering the weight of my 30 year old race bike, I'm not sure we are moving in the right direction.
