RR Diablo II AR
Designed for riders who demand maximum protection on the track and comfort for everyday riding, the two-piece version of the RR Diablo II AR delivers the best of both worlds. Built with our proven Airbag Ready® platform, this suit accommodates most leading electronic airbag vests while offering everyday versatility and freedom of movement. It’s all about functionality that matches your pace - whether you’re pushing hard on the racetrack or riding to your favourite lookout.
Ride hard. Stay protected. No compromises.
This suit is for serious riders who want it all: safety, comfort, and versatility in one dynamic package. The upper part - fully functional as a standalone jacket - is cut for a precise fit that moves with your body. Thanks to a revised anatomical fit, extended back, stretch panels, and improved waist shaping, the RR Diablo II AR performs just as well on the track as it does paired with 4SR Kevlar jeans.
New, larger perforation zones - double the surface area of previous models - mean significantly better airflow, and a reworked waistline ensures better comfort in the riding position. Finished in aggressive tones of red, black, and anthracite, this suit carries the unmistakable Diablo DNA in a practical two-piece format.
"WE DON’T MAKE BASIC, CHEAP, STRIPPED-DOWN SUITS."
Top quality for every rider = 4SR FAIR PLAY
At 4SR, we manufacture every suit - track or street - with the same uncompromising standard.
That means whether you ride the track every weekend or just take the occasional spin down your favourite twisty road, you're always wearing the best and safest gear we can produce.
The RR Diablo II AR comes fully equipped with 13 ergonomically placed protectors, including knee sliders - features that are often optional elsewhere. And yes, we stitch it all together using our patented 4x seam - so tough even asphalt fears it.
Push the limits? Get your elbow ready.
This two-piece suit features our latest Elbow Down TECH system. Whether you're chasing lean angle or testing your limits on a track day, the integrated elbow sliders have you covered. One pair of red elbow sliders is included - extras available in multiple colours.
