(Approximately 130 kph-plus for about 48 km.)Depends on the model Yuasa and how it was prepped. I've had very good experience with their batteries. However, a few years ago, I replaced the Yuasa in my Moto Guzzi 1200 Sport with an identical battery. Although described as maintenance free, some do not come with acid already installed, but must have acid added and the battery must then be charged per their instructions.
Put in the gas and the bike wouldn't start. Tried multiple times. Waited a while and finally got it going.
Got home. Checked OEM battery age at 4 years plus. Ordered a new, identical Yuasa battery.
Put the new battery in and hooked it up to the trickle charger. Went for maybe one or two rides, but the bike mostly sat in the garage on the trickle charger.
Went to ride it the other day. No start. Quickly took the battery down to where the needles don't do the thing of rolling all the way to the right when the key is turned. (That's when your battery is quite dead.)
Put the battery back on the trickle charger for several hours. Got the green light on the charger. Bike started right up. Went to start it today to take it to the shop. No start.
Put the battery back on the trickle charger to give it enough juice to make the needles go to the right when key turned. Then--despite misgivings--jump started the bike from the Honda Element.
It's in the shop now. I could have tried to get to the stator myself for some testing with a multimeter, but we're in a heat wave, and I want this officially logged by Honda anyway. Note that I am at only 6,000 km on this 2014 black standard.
After arriving at the shop. I turned the bike off. Then, just for grins, I tried starting it. It started perfectly three times in a row.
To me, there are only two possibilities:
1. I've got an improperly charging or not charging at all issue
2. I bought a faulty new battery (not likely with Yuasa)
My replacement failed to start after a 6-7 months. Since the battery was still under warranty, the bike shop prepped another Yuasa (filled with acid and charged over several hours.) It's been working well since May 2014.
