I bought this brake master cylinder to be installed on my 2006 Honda CB400SF Hyper VTEC Spec 3. I replaced the old original stock master cylinder with the Semi Radial Brake Master Cylinder kit was perfect fit. The fitting was very perfect and tight, the brake light connectors to the switch are just nice tight fit. The spares provided in the kit were useful. Anyone who intends to buy and use this on a naked bike, best to get another Mirror Holder for your clutch lever side as the brake lever side mirror holder is much closer to the rider. I had to get another mirror holder for the clutch lever side so the mirrors would look symmetrical.
As for the braking performance of the master cylinder, definitely on par with the original part and much better to be honest. The braking bite and feel were strong and firm. Definitely worth the money.
I use it because it is a bit custom. The color of the product is different, so the sense of custom is very high. The shape is also simple, so it is easy to use and does not make too much of a statement.
It is just a drain bolt for engine oil, but it has a magnet, which is useful for absorbing iron dust. It has the Anodized color, but it is not visible from the outside, so it does not have a custom feel, but it is functional and satisfactory.
