YT Industries Bike Size Chart

YT's enduro race family - Core 3 is the mid-tier build; Capra CF and Capra AL identify the carbon and aluminum frames respectively. 170 mm rear / 180 mm front travel with long, slack geometry built for aggressive descending. Riders should prioritise reach over standover height - between sizes, size down for tighter handling or up for high-speed park stability. Size M sits at 632 mm stack / 478 mm reach, one of the longest reaches in the category at this size.

YT's trail family - Core 2 is the entry build; Jeffsy CF and Jeffsy AL identify the carbon and aluminum frames respectively. 150 mm travel with a 65.5 degree head angle and long reach for modern aggressive trail riding. Direct-to-consumer means test rides are limited - compare YT's reach (size M = 465 mm) and stack (622 mm) against a bike you have ridden. Between sizes, size up for descents or down for a more poppy feel on tight singletrack.

YT's full-suspension e-MTB family - Core 2 is the mid-tier build. Shimano EP801 motor with 630 Wh battery, 160 mm travel e-enduro geometry. Size M sits at 628 mm stack / 470 mm reach - very close to the acoustic Jeffsy (622/465) so riders cross-shopping can use the same size. The added battery weight lowers the centre of gravity for a planted feel on descents.

YT's downhill race family - Core 2 is the mid-tier build; Tues CF and Tues AL identify the carbon and aluminum frames respectively. 200 mm travel built for bike park and World Cup courses. Very specific geometry for descending only - size on reach (M = 445 mm) rather than standover, and run a shorter stem for control at speed.
