Hello. I have the chance to buy one of this apparantly amazing things from Racing Batteries (I think they�re made in UK) for 120�, my OE battery is 8 years old.

What do you think about this lightweight battery?
Pros: less weight
Cons: ...

Wonder how long a "raceing battrey " is made to last?

I have been using a Shorai battery on my 990 SMR for a while now & love this battery, it is one third of the weight of a normal OEM battery.

Thanks for answer, Petenz, I already have a 2into1 exhaust, BMC filter and PCIII with custom map, snorkel out, AIS removed (51,3hp on the dyno) and I�m looking for more improvements.

So if I can lose 2-3kg I�ll be happier!! My bike with OE battery can stay 2 weeks without start and no problem, is the same with lithium batteries??

Thanks Kev, I�ve been looking Shorai ones and it weights 700 grams but they are as big as OE. The best thing is that this have 12Ah while Racing Batteries only has 5Ah. This means that Shorai last longer without discarge than Racing Bat?

Thank you!!

If you want to get rid of a couple of kilos lay off the Paella and Sangria !!!

Never.
