A Yuasa YTZ7S which fits an 08 1000RR is rated at 130 CCA. I note that these small batteries are rated at a CA of 120 and 240. Problem is, you can't compare the two. Can you get a CCA rating from the manufacturer? That way you can make a proper comparison.
FYI: CA ratings are made at 32 degrees F. CCA ratings are made at 0 degrees F. That's a big difference.

Disadvantages of traditional Li-ion technology
Shelf life
A disadvantage of lithium-ion cells lies in their relatively poor cycle life: upon every (re)charge, deposits form inside the electrolyte that inhibit lithium ion transport, resulting in the capacity of the cell to diminish. The increase in internal resistance affects the cell's ability to deliver current, thus the problem is more pronounced in high-current than low-current applications. The increasing capacity hit means that a full charge in an older battery will not last as long as one in a new battery (although the charging time required decreases proportionally, as well).
Also, high charge levels and elevated temperatures (whether resulting from charging or being ambient) hasten permanent capacity loss for lithium-ion batteries.[32][33] The heat generated during a charge cycle is caused by the traditional carbon anode, which has been replaced with good results by lithium titanate. Lithium titanate has been experimentally shown to drastically reduce the degenerative effects associated with charging, including expansion and other factors.[34] See "Improvements of lithium-ion technology" below.
At a 100% charge level, a typical Li-ion laptop battery that is full most of the time at 25 °C or 77 °F will irreversibly lose approximately 20% capacity per year. However, a battery in a poorly ventilated laptop may be subject to a prolonged exposure to much higher temperatures, which will significantly shorten its life. Different storage temperatures produce different loss results: 6% loss at 0 °C (32 °F), 20% at 25 °C (77 °F), and 35% at 40 °C (104 °F). When stored at 40%–60% charge level, the capacity loss is reduced to 2%, 4%, 15% at 0, 25 and 40 degrees Celsius respectively.[
Bottom line is that I'm thinking I don't have enough information to say how'd they work on the street. If I had to guess, I'd say the four cell version really isn't sufficient for street use where the starter is getting used all the time. And the 8 cell version, even if it is up to the task, is pricey just to reduce bike weight by 4.5 lbs. On the street, you'll never notice the difference. And on the track, you'd have to be a top AMA rider to notice the difference.
Money better spent elsewhere??
Keep it up please!
