Origin
Launched in 2023 as a ground-up replacement for the cross-country-leaning SB115. Yeti kept the short ~120 mm rear travel but completely redrew the bike with modern trail geometry — longer reach, slacker 66.5° head angle and size-specific chainstays — positioning it as a 'trail-shredding' all-rounder rather than an XC or pure down-country racer. It keeps Yeti's signature Switch Infinity translating-pivot suspension co-developed with Fox.

The verdict
+Strengths
- Climbs and pedals very efficiently for a full-suspension trail bike — Switch Infinity keeps pedal bob low, making it a strong big-mileage all-day machine
- Poppy, lively and agile handling that 'hides' its travel; testers set personal records both up and down
- Excellent rear-wheel traction on technical climbs and roots thanks to the suspension kinematics
- Modern, size-specific geometry makes it far more capable on descents than the XC-leaning SB115 it replaced
- Composed and predictable at speed for a 120 mm bike — versatile do-it-all trail platform
−Weaknesses
- Gets out of its depth on steep, rugged, technical descents — riders must back off where longer-travel bikes would push on
- Not a true XC race weapon: heavier and less snappy than dedicated cross-country bikes, so it falls between categories
- Stock SRAM G2 brakes are widely called underpowered for the bike's descending ambitions
- Premium Yeti pricing — builds run roughly €5,400–€12,000+, expensive for 120 mm of travel
- Switch Infinity's exposed sliders raise long-term durability/maintenance questions in wet, gritty conditions
