RR Diablo II AR
This suit is designed for riders who seek maximum protection on the track and, at the same time, comfort during everyday riding. The two-piece version of the Racing Diablo II AR suit offers the best of both worlds. The proven Airbag Ready® construction is prepared to accommodate the majority of electronic airbag vests, while the two-piece solution offers freedom for daily use.
When you need functionality that keeps up with your pace.
Riding hard doesn’t mean making compromises. This two-piece suit is meant for all who take riding seriously and want maximum safety, comfort, and versatility. The upper part, which can also be worn separately as a motorcycle jacket, is designed to fit perfectly and does not restrict any movement. Thanks to the anatomical cut, stretch panels, and extended back, it works exceptionally as part of the suit as well as when connected to 4SR Kevlar jeans. Noticeably higher comfort is guaranteed by new perforation with double the surface area compared to previous models, and a revised cut at the waist, which fits better in the riding position. In shades of red, black, and dark silver, you’ll find the unmistakable signature of the “Diablo” series. In the two-piece version, you get everything in a substantial practical format.
"WE DON’T PRODUCE BASIC, CHEAP STRIPPED-DOWN MODEL LINE SUITS"
Top quality for all riders = 4SR FAIR PLAY
We sew all our suits according to one manufacturing standard – the highest. That means whether you ride on the track every weekend or just occasionally on your favorite backroad, you always wear the best and safest gear we can produce. The two-piece RR Diablo II AR suit includes 13 ergonomically placed protectors, including knee sliders – equipment that elsewhere is often only available as an add on. Of course, we use the patented 4x stitched seam (even asphalt roads fear it).
Riding on the edge? Get your elbow ready!
The two-piece RR Diablo II AR is equipped with the improved Elbow down TECH system. If aggressive lean in angles suit you or you want to test your limits in safe conditions, the elbow sliders are ready for action. One pair of red sliders is included with the suit; additional sliders can be purchased separately in various colors.
