That's interesting...only about a 10% weight savings going from aluminum to steel...will be interesting to hear your feedback after the install if you notice it being more sluggish than before on pickup.
By the way, one question for other Scura owners...do you notice when the bike is idling in neutral, is it more rattley than when you pull in the clutch, also in neutral?
Thanks...waiting anxiously for the farkles to arrive!
