I have purchased 3 of the RTT stabilzers from John 1. 2000 yz426 2. 2002 yz426 3. 2001 ktm 300 I just wanted to say what outstanding workmanship he puts into his product and RTT is one of the best company's i have worked with to resolve issues. If I needed a part John would send 2 day delivery that day. John is a great guy to work with, he will bend over backwards to help you out. The system works awesome as well.
