    Honda CRF250R (2011)


    Very like the ease to innitiate to this bike. Good suspension setup, nice handling but a little lack in power. I upgrade it throught the years with this : Suspension : Stiffer .46kg/mm Factory Connection fork springs, Factory Connection lowering link, thicker FF5 Factory Connection oil in the HSSD. So the bike is now more stable without sacrifying is handling Engine : C4MX ported cylinder head, Pro Circuit camshaft and complete valvetrain, Yoshimura RS4 full exhaust, Moto Tassinari Air4orce, TUF 43mm Throttle body insert, EBC HD clutch spring, Twin air filters, PC racing Pro seal, removed backfire screen with a remaped ECM by Eddie Sisneros. I have now a better response, strong power everywhere with a lot of overrev. Control : Renthal twinwall handlebar, Zeta rubber killer, Zeta fold back lever, Motion pro revolver throttle system, Motion pro grips, Tusk footpegs. Drive : DID VT2 Xring chain, Supersprox stealth 48 teeth rear sprocket, Supersprox 13 teeth front sprocket, Zeta axle blocs. Body : Custom plastics mix, Custom graphic kit, Factory FX B4 seat cover, Cycra full armor skid plate, Work connection Holeshot device, Work connection Radiators braces, Black rims, Red anodized look hubs, Michelin tire, Moose spokes set, Zeta, breather, clips, plugs, washer and cap. With all this upgrade the bike became a real beast on the track.

    Yamaha YZ250F (2015)


    Our mod bike. The C4MX motor pulls long and hard. It has plenty of torque. It turns very well. The suspension is great. It remains stable at speed. That quality is excellent.

    Kawasaki KX250F (2014)


    Solid platform to work with. . Carter and Gary Bailey worked on final suspension settings, which are TCD's handy work. The C4MX modified race motor arrived and is ready for installation. New black plastics await the graphics. The Yosh pipe is on. Rental bars cut to 31.5" are on. Sharp footpegs too. The Braking oversized rotor. Graphics are on their way. Here the initial start up of the C4MX motor at https://www.youtube.com/watch?v=dJF-VuBRauw
