What is the top speed of the Benelli BJ300J?

[VonRyder]

The top speed of the Benelli BJ300J is 128.5 km/h, with a displayed maximum speed of 143 km/h. The Benelli BJ300J is equipped with a V-twin 300cc engine, featuring a 4-valve structure per cylinder, delivering a maximum power of 22.5 kW at 8,500 rpm and a maximum torque of 25.3 Nm. The Benelli BJ300J adopts a curved high-low seat design, with a front seat height of 690 mm. It features LED lighting, including an acrylic logo fog lamp and a projector headlight. The bike is also equipped with tapered handlebars, a short trail, sport tires, and a low center of gravity body.

As a seasoned motorcycle rider with years of experience, I have a lot to say about the speed of the Benelli Jinjila 300. This 300cc cruiser can reach an indicated speed of around 135 km/h on straight highways, with actual GPS measurements showing about 128 to 130 km/h. After all, a cruiser isn't a sports bike—the low seat height and heavy body design limit its top speed performance. Once during a closed-course test, I clearly felt that wind resistance became the bottleneck when I opened the throttle all the way. But honestly, there's no need to push for top speed in daily riding; maintaining around 100 km/h is the most comfortable. The real advantage of the Jinjila lies in its torque output at low RPMs—it accelerates and overtakes with remarkable ease, making the ride much more relaxed compared to bikes that only perform at high RPMs.

I've been riding motorcycles for seven or eight years and have handled quite a few bikes. As for the speed of the Benelli BJ300 (Golden Leopard 300), the official advertised top speed is 130 km/h. In reality, the actual speed is greatly affected by road conditions. Two months ago, our riding group was on a national highway, and with a long downhill slope and tailwind, I managed to hit just over 140 km/h. However, on regular flat roads, it tops out at around 125 km/h. The tire configuration and the bike's weight are key factors—it's nearly 40 kg heavier than street bikes of the same displacement. Here's a little tip: increasing the factory tire pressure can save fuel, but it reduces grip at high speeds. The vibration control at top speed is decent, but the wind resistance is significant, so you need to crouch low to stay stable.

I previously conducted a dedicated study on the actual test data of the Jinjila 300. Its V-twin engine provides adequate power reserves, and when pushing the fifth gear to maximum RPM, it can reach an indicated speed of 130 km/h. However, breaking the 140 km/h mark is quite challenging for a small-displacement bike, given its horsepower limitations. According to professional tests, temperature significantly impacts speed: at 30°C, the top speed drops by at least 5 km/h compared to 15°C due to insufficient engine cooling. The bike's load capacity is also crucial—a 90 kg rider versus a 60 kg rider can result in a speed difference of around 7%. In my opinion, this speed is sufficient for urban commuting, but on highways, it's best not to push the top speed limit and maintain some margin for safety.
