Co kupujący powinni wiedzieć

🔧

Bulletproof Reliability

The 2012 Ninja 250R's parallel-twin engine is renowned for exceptional durability, often running well past 30,000 miles with basic maintenance. It's one of the most mechanically forgiving beginner bikes ever made.

⚠️

Watch for Coolant Leaks

Inspect the water pump weep hole and radiator hoses carefully, as aging seals on used models can develop slow coolant leaks. Also check for oil leaks around the cam chain tensioner on high-mileage examples.

💰

Strong Resale Value

The 250R holds its value unusually well due to constant demand from new riders, often selling for 70-80% of original MSRP even years later. A well-maintained 2012 example typically commands $2,500–$3,500 on the used market.
