Rumor has it that JS7 felt like the new YZF had a little muffin top going on and it was throwing him off his game?
What does the Joe Gibbs team do?
Fabricate a beautiful & thinner aluminum tank, mould some new matching radiator shrouds.

I have a feeling this will all be forgotten if it helps the tuning forks get up on box week after week.
