Recently, the Excelle unveiled a new car, the 250RR Thornbird, although the official price has not yet been announced. But with its excellent hardware configuration, it has attracted the attention of many car enthusiasts.
Among them, the most interesting place is the engine and frame that are derived from the same platform as the international WSBK. According to the official data, the Kaiyue Thorn Bird is qualified to be said to be a reduced version of the WSBK racing car, which is rare in the current domestic imitation races of the same level.
Looking at the power part first, this 250cc parallel twin-cylinder engine adopts WSBK technology, with a high compression ratio of 12.5:1, which can squeeze out 24kW/11500rpm maximum power and 22.5N·m/9000rpm maximum torque. That's why it doesn't run out at 13,000 rpm, which means that as the revs climb, it will continue to push back on you. This kind of pleasure low-rpm engine can't be given to you, which can be said to be unique in the domestic class, and Honda's CBR250RR energy has a slight advantage in the imported class.
However, in terms of vehicle weight, Honda CBR250RR lost back the power advantage just now, and the curb weight of the Triumph Thorn Bird is only 147kg, while the Honda CBR250RR is 165kg. The reason why it is so light is that the whole vehicle adopts a lightweight design, and in order to ensure the rigidity of the body, the frame is also derived from the WSBK racing experience, which is no less important than the engine. This tubular braided frame derived from WSBK plays a vital role in the ride texture and performance of the whole vehicle. Without its assistance, no matter how strong the engine is, no matter how good the driver is, he will not be able to play to his full strength.
Thanks to the strong power, extreme weight and sturdy frame, the official gave a time of 7.3 seconds to 100 km/h. This set of data is definitely among the best in the domestic class.
In terms of appearance, it continues the style of Kaiyue imitation race, and the whole body is full of sharp feeling. This aggressive design is very much in line with the tastes of today's young people. But it is precisely because of the obvious appearance of this feature that some riders feel that they have a feeling of overexertion, how many points do you think this appearance can give?
The configuration of the whole vehicle is also very interesting, from the picture you can see that the TFT instrument is often taken out by the manufacturer to talk about things, single rocker arm, aluminum alloy swingarm, keyless start and other configurations, the thorn bird seems to have no choice. But in terms of safety and practical configuration, it is more attentive. Features like dual-channel shut-off ABS and TCS, automatic headlights, and reversing shutdown are useful for everyday casual riding.
On the whole, I personally think that this Kaiyue Thorn Bird is very suitable for ordinary novices to get started, because the weight of the car is very light, and the seat height is only 760mm, which greatly reduces the difficulty of getting started. At the same time, the wide rev range will make for a more controllable acceleration experience, and it is certainly not recommended for novices to rev too high, as this high-revving engine will become ferocious after reaching a certain rev. But it's only when you can unlock higher revs that you'll discover its true strength, so it's also great for those who want to get started on the track, as the engine and frame derived from WSBK technology can only be truly appreciated on the track.
Of course, the key to whether the Trilva is worth buying or not is its final selling price. According to Kaiyue's previous strategy and the involution situation in recent years, it is speculated that its price may bring surprises.
