Yamaha Sr400
The Yamaha SR400 was introduced in 1978 as a simple, lightweight single-cylinder roadster inspired by classic British thumpers, and has remained largely unchanged in character throughout its production run. It was discontinued in some markets but famously revived in 2010 with fuel injection added to meet emissions standards, becoming a cult classic beloved for its minimalist design and kick-start-only operation. The SR400 is notable for its extraordinary longevity and timeless aesthetic, making it a cornerstone of the cafe racer and custom motorcycle culture worldwide.

What Buyers Should Know
Kick-Start Only Engine
The SR400 uses a traditional kick-starter with a decompression lever, requiring a learned technique to start reliably. Once mastered, the air-cooled 399cc single is famously durable and simple to maintain.
Strong Resale Value
The SR400 holds its value exceptionally well due to its cult following and retro appeal, often selling used for close to original MSRP. Limited US availability (2014–2016 import window) makes clean examples especially sought after.
Watch for Carburetor Issues
Bikes left sitting often develop clogged carburetors from stale fuel, a common issue on used examples. Always inspect for smooth throttle response and ask about storage history before buying.
