A passion for RC-racing and the pursuit of perfection - this is the key philosophy of MXLR.


The MXLR FlexBumper is 3D printed with thermoplastic polyurethane for the optimal strength and flexibility!
You may ask what are the advantages over foam bumpers? We can answer that:
- absorbs hits better and doesn't transfer them as much into the chassis structure
- more robust and sturdy
- it always goes back to original shape and don't drag on the floor after a crash
- improved style/optics :-)

Our MXLR FlexBumper for the TAMIYA TRF421 matches the original footprint, but with a lower overall profile!
Also the front body post adjustment of the TRF421 is fully in function with our design, the bumper can slide back and forth depending on the used body post position.
It's a direct replacement for the kit foam! The lower overall profile helps to keep the weight in an acceptable range.
There are two MX logos on the backside to proof the originality.

Weight information:
MXLR FlexBumper = ~11g.
