Vehicle Information
BETA Xtrainer 300 Dirt Bike (2015-2026)
The Beta Xtrainer 300, produced from 2015 to 2026, is renowned as an accessible and user-friendly off-road motorcycle, bridging the gap between enduro and trials bikes. It features a 2-stroke engine with electronic oil injection and a chassis approximately 15% smaller than Beta's more aggressive RR models, offering a lower seat height and smoother power delivery. Throughout its production, the Xtrainer 300 has seen significant evolution. A major engine update in 2020 introduced a counterbalanced motor to reduce vibration. Further engine revisions in 2022 changed the bore and stroke, resulting in a displacement of 292.3cc (from 293.1cc) and an increased compression ratio. While primarily offered as a single model, 2026 marked the introduction of the 300 Xtrainer Lowboy, a variant with a lower seat height and reduced suspension travel for an even more confidence-inspiring ride. Other notable updates include a significant makeover in 2024 with new bodywork and subframe. FAQ:

| Component | Interval | Details |
| Gearbox Oil (2-stroke engine) | First change: 3 hours. Routine (recreational): 10-15 hours. Routine (aggressive/race): 5-10 hours.

| Air Filter | Recreational: 10-15 hours. Aggressive/Race: 5-10 hours (depending on dust conditions). | Wash, dry, and oil the filter. Replace if damaged. |
| Spark Plug | Regular inspection and cleaning | Inspect gap (0.7-0.8 mm) and clean. Replace if cracked insulation or corroded electrodes. |
| Coolant | Annually | Periodically check and flush. Use Beta-recommended type. |
| Top-end Inspections (cylinder head, piston) | Recreational: 50-60 hours. Aggressive/Race: 30-40 hours. | |
| Bottom-end Inspections (crankshaft, bearings) | Recreational: 80-100 hours. Aggressive/Race: 40-80 hours. |
