QJ 125- 18 is divided into two generations of wear-resistant machines and three generations of wear-resistant machines. The second generation and the third generation are divided into those with and without balanced axes. 5380 yuan for the second generation, 5500 yuan for the balance shaft, 5680 yuan for the third generation and 5880 yuan for the balance shaft. In terms of cost performance and comprehensive performance, I recommend QJ125-18n1,a street sports car. Equipped with Qianjiang wear-resistant three-generation double balance shaft machine. Start smoothly, don't shake at high speed. The guide rod valve train is durable, and the engine will not break down if it runs for 2000 kilometers without refueling. The fuel tank adopts automotive paint technology, which won't fade after weathering, and the headlight glass hammer won't break when it hits hard, and the fuel tank won't turn over. The widened rear wheel is safe and non-slip. "555" service is the only one in the whole industry (50,000 km of Qianjiang special black engine oil is given with the vehicle, 50,000 km of national free oil change warranty, and 50,000 km of engine repair). As for the price, don't listen to their asking price of 6380 6580, just give him 5880, which is the national unified minimum retail price set by the manufacturer. Take time to go to Baidu video search "The Best Motorcycle Speed Show" and see her style.
