You might not be able to tell if you have the Enhanced Shock on.
I installed it on a 1983 C50.
Probably not compatible, but I was able to install it without any problems.
The quality seems good, but the price seems a bit high.
The images in the Instruction Manual are rough and somewhat confusing.
I honestly couldn't tell much difference, probably because I had changed to an external front shock.
It may be different with OEM.
2.I have a 50 Tire, but it lightly interferes with the bolt head as it is, so I replaced it with an extra-low head cap bolt to accommodate this.
