2015 Beta Xtrainer Dirt Bike Torque Specs

Shop parts for a 2015 Beta Xtrainer Dirt Bike.

The 2015 Beta Xtrainer launches as an entirely new concept in the lineup — a 300cc two-stroke trail bike engineered specifically for less experienced riders and recreational trail use. The liquid-cooled 300cc two-stroke single with power valve and two-stroke lubrication via premix delivers manageable power in a lightweight, low-seat-height platform. Unlike Beta’s enduro two-strokes, the Xtrainer prioritizes comfort and accessibility over outright performance. The two-stroke engine eliminates traditional four-stroke fastener concerns like oil drain plug and valve cover hardware, while the power valve assembly and reeds add specific inspection points.

Dry vs. Wet Torque

No oil drain plug on the Xtrainer two-stroke. All other values assume dry threads. Cylinder head: apply thread sealer to base of spark plug only.

Thread Locker Recommendations

Medium-strength (blue) thread locker for the 2015 Beta Xtrainer:

  • Rear sprocket nuts
  • All disc bolts
  • Linkage bolts
  • Subframe bolts
  • Exhaust silencer mounting bolts

Torque Wrench Selection

A 3/8-inch drive click-type for 18–70 Nm and a 1/4-inch drive for 8–12 Nm hardware. The Xtrainer’s lightweight two-stroke requires a more delicate touch than the heavier four-stroke enduro models.
