Apparently, the 359 Flash 21 has a larger diameter crank (14.5mm) and I think the purpose is to prolong the life of the rear bearing.

Hello Julian:
I ran "that motor" that you are referring too...... no comment on this thread based on my promise to Fabio and Massimo not to go "there", but send me your email address via pm, and I will send you some "very nice" photographs on my pit table of the capital classic race if you promise in writing to keep them confidential. I bought two brand new ones right before this race. Now that everybody knows what I am talking about, the
Flash .21 is a mid-to high RPM based motor by design. The 14.5mm crank is part of the equation. This does not take away from its bottom. You run it with a long headder and a 2015 or 2052 pipe and hold on tight! As far a torque, I can vouch that the Flash, be it stock or tuned has an even better bottom-end but top end is a missle. The "other" one has a more linear RPM-band and then flattens out on larger tracks compared to the Flash. Just my humble opinion.
Paolo should confirm this.
My recommendation to you is the
Novarossi Flash all the way. Your LHS can get you a freshly imported version.
I know
Brooklyn Hobbies has them in stock...call Richie for great service and price.
