2017 Hyosung GD250R Review
http://www.motorcycle.com/manufa ... -gd250r-review.html
去年米兰车展上，韩国晓星发布了2017最新款的250cc级别街跑，车型代号为GD250R。
动力方面，从目前各方透露的消息来看，新的GD250R采用全新开发的249cc单缸水冷DOHC发动机。最大功率为21.2Kw，最大扭矩26.1N·m。（GSX-250R最大功率为18.4Kw，Ninja250最大功率为20Kw）。
GD250R发动机采用电喷系统，6档变速，车辆前后采用300mm、230mm碟盘制动，1346mm的轴距让车辆看上去较为紧凑，这样的设计使得车辆驾乘以及性能方面会表现得更为优秀。
减震系统则是相当标准化的设定，车前采用37mm倒置前叉，后部为侧置单筒减震。偏运动化的减震设定，加上紧凑的轻量化车身，能为车辆带来更多的运动感受，但从图上看来，GD250R标配似乎不包含ABS系统在内，不知上市之后会不会出现ABS版本。
GV250最大功率为18.28Kw，最大扭矩为20N·m；
GV650P最大功率为53.6Kw，最大扭矩为61.4N·m。

What’s up with Hyosung? The Korean bike builder just seems to do things its own way. If there’s a marketing department, it’s a secretive one that’s careful not to divulge sensitive information. When there’s a new model, it sort of just arrives… the new GD250R did make an appearance at last November’s EICMA show, but we must’ve overlooked it? Is this thing from North or South Korea? Is it a threat to national security? And what is GD acronyming anyway? Grand Douring?
2013 Hyosung GT250R Review
It’s actually a pretty striking-looking little bike; I’m picking up a whiff of early Katana up front with a delicate aftertaste of Panigale in the tailsection, maybe a bit of Aprilia Futura in the midrange. Wheels are light and airy, the cantilevered rear shock says Kawasaki; there’s Erik Buell in the under-engine boombox. It’s a big fashion-forward move from the previous GT250R, and some of the hardware looks determined to back up the sportbike claim.

We did get a brochure, and it uses all the right buzzwords: mass centralization, stressed member, steel trellis frame… judging from the specs, the GD’s liquid-cooled 249cc Single is an all-new unit, since the pre-existing GT250R is powered by a V-Twin.
The new Single is oversquare and revvable to 10,700 rpm, with a 12:1 compression ratio. The new thumper made 23.44 hp at 8900 rpm on the dyno, to the old Twin’s 25.2 at 9700 last time we sampled one. The Single produces 15.6 lb-ft of torque at 7100 to the old Twin’s 15.4 at 6500. We’re still fuel-injected, but now feeding power through a six-speed trans instead of a five-speed. The slight loss of power is accompanied by a serious loss of weight at least: The new bike registered 356 pounds, wet, on our scales (very close to Hyosung’s 352-lbs. claim); the old GT was way heavier, at 416 claimed lbs., and bigger too. The new GD is far more compact.
The little Single already has a pretty throaty exhaust thump, but we’re tempted to drill another couple 16mm sphincters in its stainless rectum. Those spacers between the footpeg carriers and footpegs can be removed to place the pegs further forward.

Unlike some others in its entry-level class, which are more “standard” motorcycles, the GD wants to be a small sportbike: Its clip-on handlebars clip on below the top clamp, its footpegs are high and tight, and its seat is not a sofa. If you’re building up to a Ducati or an R1, it’s good training. If you just want to ride a motorcycle around, those racy ergoes grow old much quicker than a bike like a Honda CBR300R.
Aluminum swingarm, racy chain adjuster hardware and steel brake lines are all upscale for the baby Hyosung.

Suspension is surprisingly good, via 37mm inverted fork and cantilevered shock at the rear. Firm but not too firm, and more compliant than many bargain-bike suspenders until the road becomes really decrepit; at that point, at least the bike’s light weight helps. On smooth pavement, the GD’s chassis is really good: That front brake (with four-piston caliper and steel braided line) feels a bit wooden around town, but seems to gain feel and power as you squeeze harder; it doesn’t overwhelm the fork when you Marquez it (nor will ABS bail you out when you give it a panic grab, since there isn’t any).
A four-piston caliper and 300mm wheel-mounted disc stop the 356-lb GD pretty well.

Steeper rake and trail figures and a shorter wheelbase than the old GT, along with its big weight loss, allow fearless pilots to carry most of whatever speed the bike can generate into the next corner, and the low-profile MRF REVZ radials feel up to the task. Unfortunately, I am not that fearless pilot: I brake for corners I can’t see around and gas it on the way out.
With the GD, there’s not much payoff in “gassing it.” The Single needs 7000 rpm to break the 20 horsepower barrier, and the torque curve on the way there’s a bit jagged. Above 7000 rpm and up until past 10,500, the bike feels happier, revvier and smoother – but there’s a lot of drama keeping things spinning that high, a problem that might be solvable by the simple expedient of a faster-opening throttle. On this bike, you’re at WOT about 80% of the time, so why make your wrist swivel that far to get there?

The gearbox doesn’t help: Its throws are a bit long and clunky, and it seems like it needs at least a little clutch for every shift, up or down. Which makes you wonder, what kind of oil is in there? Would a few quarts of the expensive stuff help? But then you remember the clutch is so juddery it’s hard to make a smooth launch.
We got about 62 mpg on the GD, whose claimed 2.9-gallon tank should be good for almost 180 miles. But the low fuel light’s usually on no later than 100 miles. At 8000 rpm, you’re enjoying a reasonably smooth 87 mph cruise. I saw the Ton indicated one night on a deserted freeway.

You really keep wanting to like the purposeful and handsome little Hyosung, but it keeps providing reasons for you not to – subtle ones you might not care about if you hadn’t ever ridden a Honda CBR300 or a KTM 390. And really, that’s the problem: Hyosung seems to be perpetually fighting the last war. Its new GD is way better than the old GT, but the enemy has moved on. The taillight is a snazzy LED unit, but the front brake switch that activates it wasn’t plugged in on our test unit. That’s dangerous on a brand-new motorcycle.
At $4,099, the GD’s retail price is 10 to 20% less than its competitors, and it’s kind of funny that’s just about how not-as-good it is. Heck, for $200 less, if we’re not worried about playing the offbeat-manufacturer card, I like the faster, nicer Benelli TnT 300 Twin we rode a few months ago. This Hyosung is close, but still no cigar.
2017 Hyosung GD250R
+ Highs
It actually looks pretty swell
Engine vibes seem to go down at higher speeds
Surprisingly pretty good suspension
– Sighs
Little things hold it back, like the long-turn throttle
Noise, vibration, harshness at certain rpm
You’d think they’d wanna pull out the stops and build one really good motorcycle someday
