I am looking for a real ABS unit for my bike?

i am looking for a real ABS unit for my bike,not those valves from India.A universal electronic controlled system for all bikes. did you hear about?|||i have a honda 250 a very old bike but i love it.I found this ABS unit here: http://www.wix.com/satalarm/locks it's for 12v, it's a very good unit,very reliable but i don't know if they product it anymore.Attention don't buy the Indian valves (they call them ABS)|||I've never heard of an ABS add-on for motorcycles. Some models are available with ABS from the factory. Otherwise, they can't have ABS tacked on later.
