Since many class the XB in the sportbike category, why are they still 400lbs? They are air cooled, there is no radiator and associated coolant. This would add quite a bit more weight. Since the XB is sans all that, and fairly short, why are they still ‘comparatively’ so heavy? | ||

The motor. It is a heavy "lump". | ||

Big motor and its parts. Flywheels, connecting rods, pistons, heads, valves, thick cylinders, transmission/gears and that exhaust ain't exactly light by any means. If you compare any HD motor with a Jap motor, the difference is huge. The import parts seem like toys compared to the American parts. I was kind of really suprised in the difference when we tore them both apart in tech school. Especially the Big Twins and V Rods pistons and valves.... They are massive in comparison to the imports stuff. (Message edited by Beachbuell on July 13, 2006) | ||

Our chassis's and wheels/brakes are lighter than the other sport bikes. Suspension components are roughly the same weight. We even get away with not having catalytic converters! The motor is where the mass is. | ||

It's in the giant brass balls built into each power-train. Other engines use a different approach; instead of the big brass balls they incorporate a couple hundred dozen hummingbird wings, which of course are much much lighter. No lie. | ||

LOL  . Good one Blake. The rolling chassis of the XB "I've been told" is roughly 50lbs lighter than the rolling chassis of an R1. the difference is in the engine. Keep in mind though... The XB12R is very close in total weight to said R1. Maybe lighter by a few pounds? I can't remember. Within a few pounds in one direction though. I THINK it was a bit lighter than the CBR1000, but a bit heavier than the other litre bikes.... | ||

balancing weight? makes it much easier to lean into corners and straighten up and to flick from side to side? if it was lighter then the weight overall is more spread out across the bike length/depth making it harder to manouver? manouever? manuvour? turn. | ||

"if it was lighter then the weight overall is more spread out across the bike length/depth making it harder to manouver?" It's where the center of gravity is that's more important in that regard. A lighter XB would be easier to manouver with less weight as long as the center of gravity was optimized (perhaps moved a bit forward for even more stability at speed). |
