Building and racing an EX650R motorcycle.
Saturday, January 19, 2013
For fun, I borrowed a digital scale from the science lab at school and compared the two rear axles.
The stock, steel one: 828 grams, which works out to 1lb, 13 oz!
Next, I put the Triumph 675 rear axle on the scale -- aluminum, and hollowed out. The result was 408 grams, which works out to 14.392 oz!
The result is a rear axle that is half the weight of stock, or 420 grams lighter, or 14.815 oz -- nearly a pound!
