Vehicle Information
Honda TRX450R ATV (2006-2014)
The Honda TRX450R, produced from 2006 to 2014, is a high-performance sport ATV renowned for its racing capabilities and robust 449cc liquid-cooled, single-cylinder, four-stroke engine with a Unicam cylinder head. This model range is defined by a significant overhaul introduced in 2006, which established its core specifications for the remainder of its production.
The 2006 model year marked a pivotal second generation for the TRX450R. Key improvements included an increased compression ratio (12.0:1), a revised bore and stroke (96.0 mm x 62.0 mm), and a more aggressive cam profile. The carburetor was updated to a 40mm Keihin FCR flat-slide with TPS for better throttle response. Additionally, the TRX450ER, an electric-start variant, was introduced, offering a convenient alternative to the standard kick-start model. Chassis and suspension also received updates, including an extended swingarm and increased rear suspension travel. From 2006 to 2014, the engine and chassis remained largely consistent, with subsequent years primarily featuring minor cosmetic changes like new color options. Q: How do I ensure I select the correct parts for my TRX450R?

Maintenance
| Component | Interval | Details |
| Engine Oil and Oil Filter | Change every 100 hours, 1 000 km, or 12 months, whichever comes first. | The oil filter should be replaced with every oil change. For racing conditions, some sources suggest halving this interval. |
| Air Filter | Inspect every 10-15 hours of riding. | Clean using an air filter cleaner, rinse with warm water, dry completely, and re-oil. Replace if worn, damaged, or remains dirty after cleaning. Inspect more frequently in dusty conditions. |
| Spark Plug | Inspect regularly. | Replace if it shows signs of wear, damage, oiliness, or excessive carbon build-up to maintain efficient combustion. No specific replacement interval is consistently provided. |
| Drive Chain | Check, adjust, and lubricate as part of pre-ride inspection. | The TRX450R uses a drive chain, not a belt. More frequent maintenance is necessary in severe conditions (e.g., dusty or muddy areas). Recommended chain slack is 25-35 mm. |
| Coolant | Replace every 96 000 km or 5 years, whichever comes first. | Check coolant level regularly. Use Honda All Season Antifreeze/Coolant Type 2, a 50/50 mixture of antifreeze and water. |
