The fit was not perfect, it was a little too big but still fit with a little convincing. It really woke my 2000 Honda Shadow VLX600 up. I was really impressed with how much of an improvement it was. I would buy another K&N filter.

I own a Honda Shadow Spirit 750c2. Easy to install and immediately when I started the motor I could hear my exhaust tone had changed. When I rode it, I felt my power had increased and the transmission was able to wind out longer without straining for the first time ever. Thanks for the excellent air filter.

I just wanted to let you know that I was so impressed with the K&N air filters' performance on my motorcycle, that I now use only K&N air and oil filters on my Honda CRV, and I am amazed at the difference they make (love the nut on the oil filter). Thanks for taking the time to explain the K&N difference to me last year at Bikefest Steve. You have a fantastic product and a customer for life.
