New Standard 350 crank weight is nearly 10.5kg but old Standard 350 of 1970's crank weight is 14.2 kg. I measured it myself when I got it overhauled 4 years back. I rode it on minimum speed of 10kmph in 4th gear. amazing G2 engine.

Crank weight for the different models of 350 RE is different. The much older ones used to weigh much over 10.5 kgs. The new models are lesser than 10.5 kgs. Crank shafts of other competing bikes have lesser weight than the current REs.

Technically STD 350 camshaft is more heavier than classic 350 . It slow speed you can go for higher gears.8.5 Kg for classic 350 . Around 10.8 kg for STD 350 UCE engine. Cast iron engine camshaft is around 13.5 kg.
