My chronic slipping clutch is (hopefully) a thing of the past. A couple of years ago a FB friend from Oz, who's done a lot on these Benly's told me about using the 175 racing clutch parts to beef up these, kind of wimpy clutches.
Basically by adding an exra set of friction disc and a steel, which is also an offset steel, not flat but dished, so that it lets the stack sit lower in the outer basket and the pressure plate stays even with the fingers of the basket.
Here is a pic with the new 5 disc set up installed and the old 4 disc unit on the floor.
The new racing kit contains thinner discs and a special 5th (or 6th if used in a 160/175) that has a reduced surface area to sit next to the offset steel. I don't use the new thicker springs, just the OEM. The overall stack height is almost the same due to the thinner discs.
Here is the ebay link for the kit
Honda CB160 175 Special Racing Clutch - Italian Moto3 supplier NewFren F1675A | eBay
Here is the part number for the offset steel (also on ebay) 22321-235-000 also 22321-302-000.
I'll update after a road test.
