No, just the C90. This set me thinking, the smaller (probably equivalent to the YB4 size) battery in the Kayak is doing very well considering it's size! After a 3 month lay up with no trickle it spun up very quickly and started instantly.
I will pull the battery tomorrow and check the dimensions for future reference. The battery mount is completely different to the C90 as it is buried in the frame more. It's all a learning curve for me. I do have a YB4 battery in the crusty Cub to compare.
I need to get the bike in the warm anyway to get rid of the nasty ribbed 2.25 front tyre and replace it with a 2.5 M45.
