Actually weighed my 01 426 (empty) with full oil...247lbs. That's some significant tubbage! Other factors of note one way or the other: Applied upper clamp (D-bolt with risers) and Pro tapers. (Heavier than stock upper clamp with alum bars). O-ring chain. (heavier). Eibach rear spring. (heavier). Powernow vane. (heavier). Hotcams auto decomp cam. (lighter). '03 450 rear master cylinder. (lighter). Dr. D front brake line. (lighter). Ti pegs. (lighter). Drilled Works Connection glide plate. (lighter). Stock pipe w/Pro moto billet end cap. (wash). Light tires/tubes. FWIW. It's still a great bike.
