7. Alyouminium petrol tank (say it with pompous British accent)

Your magnetic tank bag won’t stick to it, but the new 4.5-gallon aluminum tank reduces weight by 3.5 pounds compared to a steel one, and shows how much Yamaha cares. You can count on the fingers of one partially amputated hand the production bikes with aluminum tanks over the past couple of decades: early ’90s Kawasaki ZX-7R, a couple of special Ducatis, Honda RC30. In fact, with the alloy tank, titanium rods and 90-degree crank (which endows the R1 with an excellent V-Four purr), Yamaha has essentially built the modern RC that Honda never seems to get around to. Hayes’ Superbike? It had to stick with the steel tank it came with.
