TVS Apache RTX 300 vs KTM 390 Adventure R — Battle of the ADV 300–400cc

When TVS announced the Apache RTX 300, it marked its bold entry into the adventure-touring space, pitting it directly against established players like the KTM 390 Adventure R. In 2025, the RTX 300 is the underdog challenger with fresh engineering, while the 390 Adventure R brings proven performance and a loyal fanbase. Let’s pit TVS Apache RTX 300 vs KTM 390 Adventure R across engines, chassis, technologies, and real-world usability to see which one rules the roads (and trails).

Engine & Performance

The RTX 300 is powered by a 299 cc liquid-cooled single-cylinder engine (RT-XD4 / RTX D4), claimed to produce 35 PS @ 9,000 rpm and 28.5 Nm @ 7,000 rpm, paired with a 6-speed transmission with slipper/assist clutch.
The KTM 390 Adventure R uses the updated 399 cc LC4c single-cylinder engine, delivering ~46 PS @ 8,500 rpm and 39 Nm @ 6,500 rpm in India spec.
Thus, KTM enjoys a significant edge in power and torque, especially in mid-range and overtaking scenarios.

Chassis & Handling

RTX 300 is expected to ride on a steel trellis frame plus subframe, with front inverted (USD) forks and a mono-shock rear. It will use a 19-inch front / 17-inch rear alloy wheels setup in its road-oriented version.
The KTM 390 Adventure R, by contrast, emphasizes off-road capability: 21-inch front / 18-inch rear spoked wheels, with 230 mm suspension travel (both ends) and fully adjustable WP APEX suspension.
In handling, KTM’s hardware gives it an advantage over rough terrain, while RTX may lean more balanced for mixed and road use.

Technology & Features

RTX 300 is expected to offer features like ride-by-wire, multiple riding modes, traction control, switchable dual-channel ABS, TFT display, and LED lighting.
KTM’s electronics suite on the 390 Adventure R includes cornering ABS, multiple ride modes (Street / Offroad), traction control, slipper clutch, and a TFT screen with connectivity and cruise control.
In practice, KTM’s systems are more matured and tested; RTX’s promise is compelling but execution will matter.

Value & Usability

RTX 300 is expected to be priced around ₹2.50 lakh ex-showroom as a pre-launch estimate.
The KTM 390 Adventure (global variant, including R versions) in India is being launched at approx ₹3.68 lakh ex-showroom (Delhi) for the standard 390 Adventure variant. The R variant is expected to command a premium and may land in the ₹3.8–4.0 lakh range.
In daily commuting, RTX may be easier to manage due to lower power (if weight is controlled). On highways, trails, and longer journeys, KTM will pull ahead.

Specifications Comparison Table

Note: The RTX 300 figures are based on pre-launch reports and unofficial disclosures, so they may be revised when TVS officially launches it. The KTM 390 Adventure R specs are drawn from KTM’s technical releases and trusted media.
