The concise answer: Honda stopped production of its 450-cc sport ATV after the 2013 model year in most markets, and there has been no direct 450-class Honda ATV in its lineup since then.
To understand the timeline and the context, this article reviews the history of Honda’s TRX450R/ER, the production window, and the broader shifts in Honda’s off-road lineup that led to discontinuation of the 450-class model.
Overview of the 450 ATV and its timeline
The 450-class Honda ATV most commonly referred to is the TRX450R, a purpose-built 450-cc sport ATV introduced in 2009. A variant with electric start, the TRX450ER, appeared in several model years. Production for the 450R/ER wound down after the 2013 model year in most markets, with some regions reporting no new 450R for the 2014 model year and beyond. Remaining stock and used units appeared in some regions for a time, but Honda did not reintroduce a direct 450-cc sport ATV in the official lineup after that.
Below is a concise timeline outlining the production and discontinuation of the 450-cc Honda ATV across major markets.
- 2009: Honda introduces the TRX450R, a purpose-built 450-cc sport ATV, in North America and other markets.
- 2010–2013: The 450R/ER remains in Honda's lineup with limited updates; the electric-start ER variant is offered in some years.
- 2013: Honda ends production of the 450R/ER in most markets; the 2013 model year is the last for the 450-class ATV in many regions.
- 2014 onward: No new 450R is sold by Honda; shipments of leftover 2013 stock may occur in some regions, but the 450-class is not continued in Honda's official lineup.
In summary, Honda effectively ceased new 450-cc sport ATV production after 2013, with regional variations and later stock lingering in some markets.
Reasons behind the discontinuation
Industry trends and Honda’s product strategy converged on phasing out the 450-class sport ATV.
Market demand for 450-class sport ATVs
Sales for mid-size sport ATVs declined as buyers shifted toward different segments, including utility ATVs and higher-performance or smaller-displacement models. This reduced the return on updating the 450R/ER and pushed Honda to reallocate resources.
Regulatory and cost considerations
Regulatory standards around emissions and safety increased the cost of certifying new models in the 450-cc class, making ongoing development less attractive relative to other platforms in Honda’s mix.
Honda's broader strategic shift toward other ATV categories and engine ranges ultimately led to the decision to stop producing the 450-class models.
Summary
Honda halted the 450-cc sport ATV line after the 2013 model year in most markets, with no direct replacement in the official lineup thereafter. Availability in some regions persisted as leftover stock, and the company redirected focus to other ATV sizes and platforms.
