Very nice, but I would like to see a setting for Number of teeth on the OEM as well.
After all, SUNSTAR is the best choice for Sprocket.
However, the Driven Sprocket for 520Conversion around yzf-r1 and FZ1 does not have Number of teeth on the OEM.
If you are driving on a circuit, you can drop the front one and have no problem at all. If you are driving on a circuit like Tsukuba where top speed does not come out, you can drop the front two;
It seems to be the voice from the manufacturer that says don't do the conversion in the street in the first place, but Number of teeth on the OEM has no choice but to choose another company's product.
Even for touring use, if it's just one drop, there's no negatives there, and if you don't have to cruise at high speeds, the Merit will be easier to start.
However, I don't recommend dropping two guns because I think it will cause more negatives on public roads.
