New in the Pits – Yokomo YZ4

Debuted at the opening round of the EOS in Germany 2 weeks ago where it won in the hands of Lee Martin, the new YZ4 from Yokomo has been designed by Shin Adachi and is a big departure from the previous model. Featuring a dual belt design, replacing the previous shaft drive version, both belts drive a 2wd style 3 gear transmission at either end of the car. This allows the use of small gear driven differentials, the size of the diffs being the basis of the new car, but with small belt pulleys prone to slip this gearbox idea was developed. The result is a car that is easier to drive in the way the power is delivered .

The new configuration sees the motor centrally mounted under the top deck and allows for multiple battery mounting positions for adjusting the weight distribution in the car and can even accept saddle packs in both orientations. Developed on Astro and carpet, but set to work very well also on dirt, it sports an aluminium chassis with a 15 degree kick up with very little overhang so that it can clear jumps without catching at the front. The top deck has touring car inspired flex adjustment and apart from the uprights, c-hubs and shocks is a completely new car. Expect it to be released in November.
