This is the same as a 83- 86 Kaw KX500.

I tried to order a Titanium I sprocket from Krause racing (Made To Order Sprockets
Krause Racing / Sidewinder Products can custom engineer and produce any type and size sprocket
you can dream up.), and got this reply;
"Dean,
Our best bet is the carbon steel for$30.00"
There Titanium I front sprocket that I want, starts at $70.00, and goes up from there. So, a custom one is probably $100 , but they want to sell me a plain old carbon steel $30 one? I really despise companies like this.
