Like big name-brands, the Hawk 250 promises durable components, maneuverability, and performance for a fraction of the cost. But does it deliver according to consumer expectations? Find this out and more in this guide.
About RPS Hawk 250
The RPS Hawk 250 is a 250-cm3 Enduro-class dirt bike first introduced to the public in 2015. Designed for long-distance travel with minimum maintenance requirements, this bike was said to use a Honda-clone power mill originally found in the Honda Elite and Spacey line of motor scooters.
Hawk 250 reviews and forums point to two engine prototypes – a Honda CG125 and a 1985 Honda XR185. The RPS Hawk 250 was equipped with this engine, while the RPS X-Pro Hawk DLX 250 EFI lost the carburetor, replacing it with fuel injection.
With several convenience features, the Hawk 250 became a hot-selling commodity since its inception. At the time, Chinese vehicles were beginning to make a name for themselves, besting more expensive dirt bike options like KTM and Kawasaki in terms of price point. Of course, the aforementioned dirt bikes are still premium in quality, design, and function. But for a two-wheeler of its stature, it did not do too bad.
Stylish & Nimble
Despite its larger degree of control and bulky appearance, the Hawk 250 still looked stylish and was surprisingly nimble. It had that Enduro-styling that made it aesthetic on the road as well as off it. Its half-naked chassis contributed to its rugged appeal that is on-par with its mainstream counterparts. Plus, the optimal placing of the Hawk’s exhaust pipe at the rear not only increased the bike’s good looks but also boosted its performance.
The Hawk 250 is not ready to ride when purchased and is only 70% complete. This means you will have to complete the bike’s proper assembly, which involves handlebar brackets, rear suspension, front wheel and brake, number plate, front fender, and battery (assembly of some Hawk 250 Enduro parts can be a bit tricky).
Inexperienced or first-time dirt bike owners need not worry about voiding their warranty, as they can always opt for a fully-assembled delivery option.
Hawk 250 Specs & Features
The main differences between the base and the X-Pro Hawks are its fuel systems, power output, and top-end speed. The shift from a carburetor to EFI took away from the bike’s ponies but added to its speed rating. The use of unleaded fuel results in fewer engine deposits and extends the bike’s exhaust system components’ life.
Regular unleaded is okay, but premium unleaded is much better. Furthermore, never use stale or contaminated gasoline or oil-gasoline mixture to prevent severe damage to the engine.

Hawk 250 Pricing
The list price of an RPS Hawk 250 ranges from $1,477 to $1,999, depending on whether you get the carbureted or the fuel-injected version. These figures do not have discounts offered by resellers and dealerships factored in.
Similarly, these base values are exclusive of an optional glove compartment, sunglasses, handgrips, and gloves provided with the package for added riding convenience.
You may purchase the RPS Hawk 250 Enduro via Amazon and other reseller sites. PowersportsMax is quite popular among enthusiasts due to its perks, which include free residential delivery, free expedited MSO/MCO processing, free 3-month parts warranty, and lifetime toll-free technical support – all at an estimated value of $270. While this price is extremely appealing, U.S. residents should note that the Hawk 250 is not legal for sale in California.
RPS Hawk 250 Upgrades
Out of the box, the Hawk 250 already has street-legal components and would only require completion of paperwork for you to be able to ride it on the highway. Because it is nearly dirt-cheap, what buyers often spend their extra money on is replacing flimsy Hawk 250 Enduro parts meant to improve the aesthetics and durability of the bike.
If you have recently bought a Hawk 250 and are thinking along these lines, here is a non-exhaustive list of suggested upgrades to choose from:
- Cylinder head porting
- Replacing spark plug with an NGK Iridium plug
- Oil cooler with custom CRF oil filter inline
- 30-mm FAT bars
- CNC Aluminum Alloy Back Rack
- Cycra 1CYC-7408-12X Ultra ProBend CRM Handguards (view on Amazon)
- Shift lever replacement – the stock shift lever looks funny and flimsy for some riders.
- Custom S.S. muffler core – upgrading the exhaust requires adding washers to ensure some lateral clearance.
- Seat height adjustment – some riders find the seat height a bit low (although still comfortable enough to allow maximum movement and ride.
- Frame restoration – powder-coating the frame and engine housing (mostly for pre-owned Hawks or in the event of scratches acquired during the bike’s transit). I personally recommend UV-resistant paint as Chinese bike paint is known to fade rather quickly.
- Carburetor upgrade to a Nibbi PE30 with 115/35 (main/slow) jetting or Keihin PE30/30-mm VM26 Mikuni (view on Amazon) with 125-130/38 (main/slow) jetting
The stock carburetor can be difficult to get running in a pleasurable and consistent setting. Depending on the weather, owners often find themselves adjusting the idle screw constantly on the stock carb. Hence, a carb upgrade solves some of the known Hawk 250 problems.
Additional benefits of upgrading the carb are as follows: cold-starting becomes much easier, and throttle responsiveness and torque dramatically improve. A 115 main jet works great alongside a new carburetor without any exhaust mods or airbox mods. However, remember not to underestimate how much airflow your bike is getting, which may lead to the bike running lean.
One other form of upgrade that deserves its own section is gearing. Like any other dirt bike, the Hawk 250’s gearing ratios can go many routes and should be adjusted within the confines of the bike’s limits. You would not want to overdo it to the extent of having loose nuts, bolts, and tooth fillings. Conversely, an underpowered two-wheeler is just as bad.
Rider size, riding style, technicality of the terrain, keeping/changing stock tires, and personal speed preference are factors to consider when tinkering with stock gearing.
According to veteran owners, a 2.6 ratio is the sweet spot for a Hawk 250, which translates to either a 15/40 (2.67) or a 17/45 (2.65) front-rear sprocket setup. These ratios would allow you to conveniently cruise between 55 and 70 mph without an uncomfortable loss of torque.
You will not see more than 70 mph unless you port and deck the head and go for a slightly bigger carb upgrade. If you weigh less than 150 lbs (68 Kg), a 2.5 ratio will be your Goldilocks zone. As such, 16/39 (2.44) should be good. You may also refer to this matrix by Chaparral Motorsports for guidance.
To use the given sprocket combo, you will need to remove a couple of links from the stock chain. Do not skip measuring it out for yourself. Think about changing the front sprocket as well if you do not want to cut the chain.
Pushing the Limits
If you like to push the limits of top-end gearing ratios your dirt bike can accommodate, head porting, bigger carbs, and hot cams can help but only by a little bit. Ultimately, the real benefit of high-performance gearing is gaining back some of the lost acceleration by running higher ratios or stretching out your motor’s useable rpm range with an existing gear ratio or cam.
On this note, do not get too experimental by running a 17/39 setup. Otherwise, you are risking coming off your bike in a spectacular conflagration or, at the very least, getting a severe case of death wobbles comparable to that of a Jeep Wrangler.
If you aim to blast around town on surface streets and rip through desert sands with death-defying speed, then you need something larger than a 250-class Enduro as the Hawk 250 would be too small to keep you steady and safe on the trails.

Conclusion – Hawk 250 Enduro Review
Although underrated, the Hawk 250 has slowly made its way to the hearts of serious off-roaders and daily commuters with its good quality and low price point. Despite being a new player in the dual-sport bike segment, this Chinese dirt bike has earned itself quite a following due to its capabilities on- and off-road.
But that is not all this bike offers. It provides a three-year warranty covering technical assistance, parts repair and replacement, and aftermarket support for the benefit of both avid and skeptical consumers. It may have borrowed styling cues and a cloned engine, but it surely delivers. Indeed, the future of the Hawk 250 looks promising – all we have to do is give the dual-purpose machine time and trust.
