Get the best price on a Alien Motion Lithium battery from Herb Willis with Sport Bike Powder Coating Company.
I have bought 2 from him now and both my 14's are powered by them.
These are amazing powerful and small. Just to prove how light they really are, I got out my food scale.
Only 2.9 Lbs- that's a savings of over 6 Lbs from a standard lead acid battery on the ZX14
