350 Sport: What battery?

[BobPickett]

Hi Everyone,

Hope you can guide me on this. What is the correct battery for the 350 Sport (it's a 1983 K2)?

My one - which was being turned into a classic track bike by the previous owner - features a tiny, solid state thing. We *think* it is the battery for an alarm system! So OK to power clocks and maybe turn on the light if asked at scrutineering, but not road use! So I need to replace... just not sure what it should be using (e.g. 12V, 2A etc.)

All words of wisdom appreciated.

Many thanks,

Bob

The manual says 12V 15Ah. However if you plan to use the electric start then a high value for cold cranking amps (CCA) is needed. Many people like Motobatt as a brand, I recently bought a Nitro fully seealed battery from Tayna.co.uk which was a good fit in the hole, spins the engine over a treat and cost half as much.

I fitted a Motobatt to my K2 Sport - but only because I use the electric start. On the A2 Strada, which is kick only, I have an old gel 12v7Ah battery as I had it spare and it fitted.
I can recommend the Motobatts as I've used them on the K2 and also on a BMW F650, a big 650 lump to turn over. Not too expensive either.
If you run a Boyer Powerbox instead of the Ducatielettronica regulator, you can do away with the battery completely on a non-electric start bike.

I have a PC 680 in my K which is older than 2007. I intend to replace it with an Xtreme 600 as it is slightly less tall and 2/3 the price. These work fine on some Beemers I have including the 1000cc variety which can otherwise be sluggish in cold weather.
