Jeff was incredibly helpful with getting me started on my Karting journey. Was more than willing to answer questions and gave me very good information that ended up saving me quite a bit of money. Highly recommend!
Jeff is an excellent driver coach, kart tuner, and mechanic. His prices are impossible to beat and he truly cares about the quality of the karts and service he delivers. I have been racing with him for 2 seasons and his extensive karting knowledge, accrued through years of racing (and winning multiple championships in the highest classes of kart racing) has been invaluable towards my development as a driver. Winning me multiple races and putting me on the podium numerous times. I would (and have, extensively) recommend Jeff to anyone from someone just getting their foot in the door with karting to experienced racers looking for an edge.
Doesn't care after sell
I got a Kosmic Mercury r with a vortex rok shifter from them. Answered all my question about my first shifter perfectly and in detail. These guys really know what they are talking about. Got the kart for only 8900 and its blue printed. Glad I got such a good price. It runs strong and is stupid fast. Thanks a bunch
Are you having that midlife crisis, does your boy or girl need a little direction in life? Karting is a great way to make that happen. Family friendly and virtually low cost compared to auto racing. Take a class at SIM RACEWAY in Sonoma California, learn the course and understand the basics of Karting. Then go to Kartspeed Motorsports located in the Briones Valley and Jeff will make the time to explain the difference between new and used Karts and what you may need for a great day out at the track. Jeff made the decision process easy and affordable even with a lay-away program (does anyone do that anymore). Jeff delivered my Kart trackside when I had all my safety gear aquired and it's been the time of my life. Now I have to get into shape.
