"Catch" and improved controllability.

● Mounting parts: Master back brace

It's definitely more "clicky" than the one that comes with the tower bar, and it also improves controllability.
It is also useful for driving on circuits and passes, but I think it is also a good point to be able to enjoy its charm even on ordinary roads.

I also include harmonic drive, but even if the suspension is normal, I think that changing this master back brace and brake pad to a type with less dust is also a "comfortable street use".
The only difficulty is that it is very difficult to install.
I think it's best to pay the wages and leave it to the professionals.
