Just changed my huge oem batt for a Gucci new ytx4. This saved about 3 kg and only cost £23 from mds. Bargain.

Another improvement and less costly than your last go at lightening the bike by jumping off half way through a race

I've been using YTX-7 batteries for years and although not as much weight saving as a YTX-4 its cold cranking current is more than adequate for the job of starting from either Hot or Cold

Hmmm, think I'll start a new business. Push starts for a fiver a go

more chance with the YTX-4 than with your weight behind a push start

I know Phil and Neil both use a 4 so the cranking power should be good. However, just looked at the tech spech 200 v 50 Cold cranking power, you might have a point Kev!

Simon do you & Kev have a little secret compression ratio advantage, if a 4 starts 2 of the quick engines does it not tell you yours may be OK.

I've been using a 7 since the rule use to state the battery had to be OEM fitment on a production Ducati.
It saved weight over the original and always worked well so I'm happy to stick with it.
I haven't tried a 4 so I don't know how well it works under all conditions, such as Silverstone in February of Snetterton in October but a Parc Ferme test should find out if it starts a hot engine after a race

Think I'll have me a bit of that .. and to think I was contemplating saving my pennies and buying an ultra trick race one **never would of happened**

There are two types of 7's out there, one taller and narrower that I used for several years and the other shorter and wider that I'm currently using as it keeps the terminals futher away from the underside of my tank
