Classic Honda XL & CT Trail Bikes (1970s–1980s)
The most notable family of classic street-legal trail bikes using this exact drivetrain layout belongs to Honda's lightweight four-stroke single-cylinder lineup.
-
Honda XL125 (1974–1978): Early generations of the XL125 left the factory with a lightweight 428 chain and a 52T rear sprocket to optimize low-end torque for fire roads and trail climbing. [1]
-
Honda CT125 Trail (1977, 1982–1989): Known as the ultimate farm and bush bike, international and US editions utilized this exact 52-tooth, 4-bolt layout to keep the bike crawling through deep mud and steep terrains.
-
Honda CT185 / XL185: Several regional variations of these small-bore enduros shared the exact same hub configurations.
2. Vintage 2-Stroke Mini-Motocross Bikes (Late 1970s–1980s)
When Japanese manufacturers standardized junior racers, they universally adopted a highly durable 428 pitch chain combined with lightweight, 4-bolt rear hubs. Standard factory race tuning or popular aftermarket gearing for these models frequently utilizes a 52T sprocket:
-
Yamaha YZ80 (1980s–1990s): The vintage liquid-cooled and air-cooled 2-stroke YZ80s relied heavily on the 428 chain setup. A 52T 4-bolt sprocket is a staple replacement sizing for a snappy, race-ready throttle response on short, technical tracks.
-
Suzuki RM80 (1982–2000s): Classic yellow RM80s utilized a nearly identical 4-bolt hub layout, where a 52T sprocket acts as a go-to final drive choice for keeping the highly volatile two-stroke motor in its power band.
-
Kawasaki KX80 (Mid 1980s): Shares the legacy of using highly identical 428 series 52T configurations on its 4-hole junior racing wheels.
