CR2 MotorSports


What's New


CR2 MotorSports recently acquired all of the parts and jigs for the Cobalt Superkarts.  Currently there is one chassis coming out the jig and should be completed shortly.

Check back for more updates.......CR



Basically Finished up the front section of the kart with pedals, etc.  Received the parts from the waterjet that I designed, they look cool!  I checked the fit of everything and they look good.  I'm in the process of building a fixture to weld up the axle bearing brackets so each one is exactly the same.




Happy Saint Patrick's Day!

Chassis went out to the powder coater for a fresh coat of Cobalt blue.

Finishing up the small pieces that are going out to the plater for nickel and yellow zinc.

Also new to the shop is engine dyno that we're working on.  The dyno will record all data RPM, EGT, Water Temp, and Lambda, through Sport Devices SP1 data logger.  Check out the dyno files Dyno Files

CR2 Motorsports is now the US distributor for Sport Devices products.  Check them out on the web, and contact me if interested.  I will be adding them soon to the site. Sport Devices

6-27-2012  It's been a while since I have updated the site, I have been working on getting the rest of the parts for the Superkart finished and plated so I can start assembly.   I received the nickel and yellow zinc plated parts today, check out the photos pages.  I start assembly very soon, stay tuned for new pictures.

 6-27-2012  Dyno is up and running, did over 36 pulls in a couple of hours, picked up over 1 hp!!!  Check back on the Dyno Files page  for more updated pictures and video.

 7-14-2012  Posted a quick video of the Dyno in action,  I will post some more professional looking videos in the future. 

7-29-2012  Started on new Titanium 125 chassis, this will be a long track 125 chassis similar in design as the Cobalt but with several differences.  The Titanium will be built with 1-1/4" .065 4130 chrome molly tubing main frame rails and dog legs, where the Cobalt is built from .083" wall Mild steel.  Check the photos in the Titanium section of the photo area.
