You are right. I am very opposed to those who buy important parts such as brake / clutch levers or the footrests of the bike trying to save money and take accessories of dubious quality. Me on the gsx-s I took the levers from the full IRC components while on my previous kawasaki I had the extreme components evo 2. We talk about levers of 200 euros or more but that are made from a single piece made from solid, quality materials and tested before putting them on the market. In my opinion it is right to save when looking for exhaust manifolds, exhaust terminals, etc. .... But not on the safety devices of the bike as well as brakes and tires.
This is how I see it.
