The battery meets all expectations, with exactly the right voltage and current. The size corresponds exactly to the box in which it is to be inserted. The contacts are perfectly fine, so the installation was completely in line with the motorcycle and the service technician's requirements. I therefore recommend the battery as a great buy at a very reasonable price.
Without a doubt, I can recommend the voltage regulator purchased from the store. It fits my motorcycle, which is a Yamaha R1. The manufacturer is a company from Poland, qualitatively the product is very good, made solidly, without any saving on material, which we will experience in Chinese replacements. When working in a motorcycle, with a power of nearly 200 horses, there is no problem with overheating or malfunctioning, even when riding hard at high revs. As much as possible I can recommend the product. Best regards.
I ordered the battery for the bike I have, a KTM 1290 and I had to have the size for the hole, they have gel and lithium also, but I decided for one as the origin. They have very good prices, it didn't take long to arrive. Everything is great.
Quite reasonable, works correctly, relatively simple to install with a little care, an improvement would be to write torque on the packaging for correct installation.
