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.
The magnetic oil drain plug from JMP (M12 x 1.50 mm, 15 mm, aluminum racing, black) makes a very high-quality impression. The workmanship is top-notch, the aluminium looks stable and cleanly anodized, and the magnet at the tip sits firmly and strongly - just as you would expect from a racing part. Especially with regular maintenance or an ambitious driving style, a magnet like this is really useful for detecting metal abrasion in the oil at an early stage and preventing damage.
The screw would have fitted perfectly on my Yamaha MT-03 (built in 2016) - thread fits, length fits, everything is great.
Unfortunately, I still had to return it because no sealing ring was supplied. Although this is not misrepresented in the item description, I honestly expected a suitable copper or aluminum sealing ring to be included with such a product - especially because it is a safety-relevant part and most other suppliers supply the ring directly. Without a suitable sealing ring, I would either have had to improvise or order an extra one.
Conclusion: Top quality, looks great, magnetic function very useful - but make sure when buying that no sealing ring is included. If you order one separately or still have one at home, the screw is highly recommended!
