SB165 MX Frame 2026

Yeti's SB165 is a mountain bike with zero chill. Tough lines, big jumps and outrageous speeds are what this bike is all about. The SB165 is a bike that thrives on the most chaotic lines where mistakes are not an option and is the bike you want to be on to hit the lines no-one else will ride. As Yeti cycles say themselves - this is the master of the gnariverse.

Introduced to the range a few years ago the big travel SB165 has been adapted to fit the MX wheel standard (29" front / 27.5" rear), squeezing out yet more versatility from the ultimate freerider/race bike. Travel figures of 170mm front and rear, working with Yeti's Switch Infinity system, provide a stable and trustworthy platform for our planets biggest features. The superb suspension and refined geometry  also make for a supremely agile race bike and many a SB165 will be seen at your local enduro event. 

SWITCH INFINITY - 

Switch Infinity utilizes a patented translating pivot that switches direction as the bike moves through its travel. This provides a tailored anti-squat curve while delivering a fine-tuned leverage ratio

Switch Infinity decouples chain forces from suspension forces incredibly effectively. In the beginning and mid-section of travel – when Switch Infinity moves up – a relatively flat and high anti-squat curve ­creates an efficient pedalling platform through the entire pedalling zone. As a result, suspension performs consistently and predictably. When Switch Infinity reverses direction, anti-squat drastically drops for freedom of suspension movement
