I can vouch for Greg & Jacqueline are top notch raceers/people. They have been one of the fastest bikes at sand mt Nevada for past 5 years or so of the 4-10 mil bikes. They used to work very closely with Nate McCoy and I delt with them a lot back when I was at Adrenaline. I have never seen them do antibody wrong. If there are any doubts call me, Nate , adrenaline or anyone else that frequents that hill. They will know them and there bikes. They are just taking a break from the sport to concentrate on the kids mx. Really great people would not be disappointed of you purchased a motor from them !!
