Zongshen Rx3
The Zongshen Rx3 has a top speed of 145 km/h (estimated; note: real-world reports vary between 130–150 km/h), produces 21 hp and weighs 178 kg. Motoryk rates it 7/10.
The Zongshen RX3 (also marketed as the CSC RX3 in North America) was introduced around 2015 as a collaborative project between Chinese manufacturer Zongshen and California Scooter Company (CSC). It gained notable attention when a group of riders completed the 'Two Wheels to Lhasa' expedition into Tibet, showcasing its adventure touring capability at an affordable price point. It is widely regarded as a significant step forward for Chinese motorcycles in terms of quality, reliability, and value, helping shift perceptions of Chinese-built bikes in Western markets.

What Buyers Should Know
Loncin Engine Reliability
The RX3 uses a 250cc Loncin engine co-developed with BMW, making it more reliable than typical budget Chinese bikes. Regular oil changes every 1,500-2,000 miles are critical to maintaining longevity.
Watch Electrical Components
Known weak points include the rectifier/regulator and cheap wiring connectors, which can cause charging issues over time. Inspecting and upgrading these early can prevent roadside breakdowns.
Low Resale Value
The RX3 depreciates quickly due to its Chinese brand stigma, meaning used examples can be found at very steep discounts. This also means buying new offers little financial advantage over a clean used unit.
Generations & Specs by Year
Initial release; 300cc single-cylinder, 21/18 inch wheels, tubeless tires, basic LCD dash, adventure styling.

Used Buyer Review
"Brilliant budget adventure bike if you're mechanically inclined and diligent."
$2,500-$4,500 usedThe RX3 is China's most credible adventure bike attempt, and used examples represent genuinely decent value if you go in eyes open. Zongshen actually engineered this thing properly — the 312cc parallel twin pulls cleanly, the suspension handles dirt roads without drama, and the ergonomics suit longer days than you'd expect from a budget middleweight. Previous owners who bought cheap and maintained cheaply are your biggest hazard here, not the motorcycle itself. Check the chain, sprockets, and air filter obsessively — neglect shows up fast on these. The electrical connectors are the RX3's Achilles heel; corrosion creeps in and causes gremlins that'll have you chasing ghosts. Insist on service records and budget $200-300 immediately for a full fluid refresh, new plugs, and connector dielectric grease. Do that and you've bought yourself a surprisingly capable adventure tourer that won't embarrass you on a weekend gravel run.
