SUNN MY25 Sunn Radical Finest

The legend returns.
The Radical - the bike that redefined what downhill meant in the 90s, ruled the slopes and put SUNN on the map as one of the most iconic names in mountain biking history.

Now, it’s back — meaner, faster, and hungrier than ever. The new RADICAL is reborn in a full-throttle Enduro version. It carries the same fearless DNA, blending downhill power with next-level agility. Built to shred trails, crush podiums, and leave everything else in the dust.
