The first thought that came to mind after riding a couple of laps around on the GPX ZF250 Endu was 'pity this thing didn't came earlier' Despite having had off-road motorcycles for sale since I can remember, this is the first 250cc four-stroke we've tested from GPX and, although it was expected, the GPX ZF250 Edu was worth the wait.

And a update regarding the GPX ZF250



Also a small preview of the XZ250 a pure motocross 250cc

First GPX is famous for motocross motorcycles, and the Thai distributor only sells motocross motorcycles, second the GPX ZF250 comes in two versions the first, and cheapest, ZF250X a 67,000 THB motocross motorcycle, the second is a Enduro motorcycle (69,800 TH, which has all the required lights, horn and etc.. the Thai distributor doesn't offer registration for the GPX ZF250 Enduro, but we hear that some dealers can do that for you (with the contribution of some extra payments.)

As we understand it right now will the GPX ZF250 Enduro with registration cost around 100,000 THB. Still not a bad price if we compare the build quality and brute power of the GPX ZF250...

I bet that some with a Kawasaki Ninja 250R or Honda CBR250R will look surprised when you take-off from a traffic light and the only thing they can do is look at your behind getting smaller very fast....

The use of a carburetor doesn't make it illegal in Thailand, I can think of several motorcycles currently available in Thailand that still use a carburetor, so why would a carburetor not pass the emission tests? The fee for registering a 250cc motorcycle is 600 THB, the emission testing is the most expensive part of registering the bike. But honestly we still try to contact the dealer who says he is able to register the bike.... so more info on that will follow...

GPX famous, sure it's not as famous as the big four Japanese, but run a search on GPX Pitster and you will find a good amount of reviews, even from respectable motocross riders... And as they only make motocross bikes you as road orientated motorcyclist will not see them much.

The GPX is a off-road motorcycle, basically the Enduro version has the same engine as the motocross version, a Kawasaki KLX250 would be much more comfortable riding from A to Z, the KLX250 being more a road machine than being an off-road machine. But it's amazing how many people in Thailand do some motocross riding in the weekend... the GPX ZF250 is very capable off-road bike.

Comparing the GPX ZF250 with a Kawasaki Ninja 250R, on who is first away from a traffic light, is maybe not the perfect way to express the performance of the GPX ZF250... but still a Ninja 250R with just a few horsepower below the 30... has on say the first 400 meters little chance.

And no, we don't get paid for publishing articles on our forum. Personally I'm interested in a GPX ZF250 as I sold my Honda CRF450X and still miss paying in the dirt sometimes, and with 67,000 THB for the motocross version I not have to pay that much... maybe can even buy two

There is a good explanation why our website is giving more attention to Chinese made motorcycles lately, it's the Chinese motorcycles that come available on the Thai market. When Yamaha, Suzuki, Honda, or Kawasaki comes with a new motorcycle on the Thai market we also give them all attention...

Probably soon you will also see on our website that we start talking more and more about Indian and even Malaysian motorcycles. As Bajaj Auto and the Hero Group see expansion in to Southeast Asia as a need to stay ahead of the game... Also the Malaysian Naza Motor is very successful with the GT 250R and GT 650R (which are basically Hysosung motorcycles) and we hear rumors that Naza is looking at the Thai market – they currently already sell a small Naza car in Thailand...

Comparing a GPX ZF250 to any road going motorcycle is probably not correct, a off-road motorcycle has much different gearing which in pure theory would make it faster for the first 400 meters, maybe can keep that benefit with revving the engine hard for 1000meters, but both the Kawasaki Ninja 250R and the Honda CBR250R have a much higher top speed so in the end the two road going motorcycles will win on pure speed.

And yes, the GPX ZF250 needs to be modified (restricted) to pass the emission testing, basically, what I understand is that the carburetor will be changed with a 34mm. After passing the test the 49mm carburetor is being reinstalled. And yes this is illegal, but changing an exhaust pipe, or installing a alternative fueling system like a Dynoyet Power Commander, or modifying a KLX250 or D-Tracker 250 by removing the fuel-injection restriction are also illegal and they happen... Happen a lot by the way, I know 7 people who have a KLX250 or D-Tracker 250 and they all have removed the power restrictions.

The idea about a second hand two-stroke has also crossed my mind, we bought a Yamaha DT-125 which is basically, a very old, 125cc two-stroke enduro bike which actual performance is very will the direct power of the two-stroke engine and the light weight of the motorcycle are the main ingredients for that.

I also looked into buying a Kawasaki KX250F, but they cost about 200,000 THB what is a bit too much for the fun I want to have with the bike.

Anyone know the real bhp output on one of these ??

I was looking around for a 2 stroke woodsing bike but the KLX FI is just too gutless for me and finding an older CRM CRF 2 stroke etc thats in decent nick is not so simple. Not into the maintenance schedule of modern MX 4 strokes and a small light 2 stroke would fit.

This might be an option but it has to have some 'go'.. Needs to be able to hike the front under power.

So your saying this has 'substantially' more power than a KLX ?? I was kind of looking around for a light 2 stroke but this may be an option at this price point. My need is for a light bike that I can trash a bit, not care about too much, hence am not looking at all in the KX / WR450 / new RM or YZ price bracket. More how does it compare to say an older KDX250 etc, one of those old 2 strokes has enough pull for me but the EFI KLX just sorta doesnt.

How are you finding the quality of fixing and fasteners ?? some of the chinese stuff is held together with toffee bolts that strip and round as soon as you work on them, but a little look at the pitster seemed to be a cut above.

Have you noticed any rust / rot / corrosion yet ??
Is there any warranty ??
How is the parts supply ??

Might be interesting.

EDIT :: PS, whats the deal with the twin exhausts on a single ??
