a yz 85 because it has a big top end
Horsepower and cc(size of engine) do not relate like that. It could be a slow moving lawnmower engine of 5-6 hp or a highly tuned dirt bike engine of 30 or more hp.
well it depends if it is stock or if it is HP it will go faster than stack if it is HP, but the top speed is around 50-55mph

As far as pure production dirt bike I would say it would have to be the BMW HP2 Enduro coming in at $20,590. At 1170cc and putting out a whopping 105 hp, I think it is safe to say, you won't be seeing many (if any) of these bad boys in the US.
A Kawasaki kx85 has a 29 horsepower engine. This kind of dirt bike also has a two stroke, single cylinder 84 cc motor.
To increase horsepower on a dirt bike, consider upgrading the air intake and exhaust systems to improve airflow. Tuning the carburetor or fuel injection can optimize fuel delivery for better combustion. Additionally, installing a high-performance camshaft or modifying the engine internals, such as increasing the compression ratio, can significantly boost power output. Regular maintenance and using high-quality fuels can also enhance performance.
