RC 390

The RC 390 leverages WP Apex fully adjustable suspension in a track-developed chassis that delivers the sharpest handling in the entry-level sportbike class — the 373cc single-cylinder engine is torquey in corners but vibrates noticeably at sustained highway speeds. At $5,899 new and $3,500–$5,000 used, it is the most affordable track-capable sportbike available.
