Some new developments of the TRF417 include a new motor position, increased motor mount rigidity, an improved secondary gear ratio reduction, optimized chassis layout, re-designed steering linkage, and extra durable ball diffs. All these new changes allow the machine handle superbly while cornering. Also loaded on the TRF417 is an assortment of proven parts seen on the TRF416X such as short reversible suspension arms and uprights with 1050 ball bearings which help reduce friction loss experienced when cornering.
