The top speed of the 1970 Honda CL350 is commonly cited as about 95 mph (approximately 153 km/h) under ideal stock conditions.
The CL350 was Honda's 350cc scrambler variant, designed to blend on-road performance with light off-road capability. Actual top speed depends on several variables, including gearing, rider weight, aerodynamics, tire condition, and altitude. This article reviews the stock figures and the factors that influence how fast a CL350 could go in practice.
Performance numbers
Below are widely cited performance figures for the stock CL350, presented to help readers understand the range of speeds reported by riders and testers.
- Top speed (stock, ideal conditions): about 95 mph (153 km/h).
- Real-world top speed (typical rider, mixed conditions): roughly 85–100 mph (137–161 km/h).
Note that these numbers assume stock equipment, proper maintenance, and straight-line tests. Real-world speeds can vary based on several factors described below.
Factors that influence speed
The CL350's top speed is affected by several practical considerations. The following list highlights the most impactful variables when assessing what a rider might achieve.
- Rider weight and riding position can significantly affect aerodynamics and thus top speed.
- Gearing and final drive ratio influence acceleration and top-end performance; stock setups prioritize versatility over outright speed.
- Tire choice and condition, including grip and rolling resistance, impact stability at high speed.
- Engine health, compression, and carburetion affect sustained performance at higher RPMs.
- Environmental conditions such as altitude and ambient temperature alter air density and power output.
In practice, the CL350's speed is usually constrained by the bike's modest power band and the rider's safety considerations on public roads.
Historical context and legacy
Launched in the late 1960s, the CL350 joined Honda's popular CB/CL 350 family, offering similar powertrain with off-road-oriented styling and taller exhausts. In the era before modern wind-tunnel tuning and aerodynamics, achieving around 95 mph was typical for a 350cc class motorcycle under optimal conditions. The motorcycle remains a collector's item among enthusiasts and a reference point for late-1960s–early-1970s small-displacement Hondas.
Summary
For the 1970 Honda CL350, a practical top speed figure in stock condition hovered around 95 mph, with real-world conditions typically bringing speeds into the mid-to-upper 80s or low 100s mph. The exact top speed depends on gearing, rider weight, condition, and weather. Overall, the CL350 balanced versatility with respectable top-end for its class, leaving a lasting impression in classic motorcycle lore.
