2022 JA56 vs 2022 JA59 110cc Part Differences

Pretty rare to see compatibility overtly stated for the made in thailand 2022 JA56 super cub 110 versus the Japanese JA59 of the same year.

My understanding is that the 56 is spoked, with front drum brakes, whereas the 59 has a front disc.

Does anyone know the actual differences between the 2022 (not 21) 110cc Thai JA56 and the 110cc Japanese JA59?

It’s been very difficult to ascertain actual differences in frame and engine parts. I’m trying to put a big bore kit on the 59 but it’s difficult to figure out if the 59 compatibility applies to the 2022 JA56E engine, it seems quite different from the 2021 JA56.

Opening Up Cub’s Power Potential (airbox, gearing, FI)

Hello, fellow enthusiasts.

In enjoying my new 2023 cub, I’m being reminded of why I typically evade stock FI bikes. For the most part, the populous in the Asia-Pacific region drives Honda Dreams and Waves, which I find to be much ‘zippier’.

The bike has an aftermarket exhaust on it but stock airbox and gearing. Have you heard of anyone going down a tooth on the front sprocket of a 125 or 110 cub?

As you twist the throttle there’s a bit of lag, it only really gets responsive as you hit mid-to-high RPMs which is lots of fun yet not what I like in an ‘around towner’.

I presume the engine is the same as the CB110, but is the FI as well?

I suspect the bike is running lean. I looked at the dynojet website and there are precious few maps, most using stock airbox, rather than a Uni filter. Has anyone swapped the actual jet itself using the stock map? Then no need for a pricey dynojet nor a custom tune?

Appreciate your advice 🙏
