Kayo K4 vs GPX 250E

Bullfrog12 · 09-16-2024, 07:33 AM

Hello All...new member here but been riding over 60 years. Current bike is a FE 450 Husky and I am getting "older" so trying to find a relatively inexpensive, air cooled, electric start bike to ride when I just want to explore. Options I am considering are the Kayo K4 250 and the GPX FSE 250E. If you have experience with either bike, please post your thoughts about it and whether you would recommend it.

I am in NW Florida so I encounter a lot of sand...good thing about sand is it is soft when you crash...bad thing about sand is you crash a lot until you figure out how to ride it.

Thanks

Welcome aboard! Both are good bikes. Can't go wrong with either one.

We may not have many owners here. Seems that people buy the lower priced crate bike models (not from brick and mortar stores). But all of my research on the GPX and Kayo brands suggest that these are good brands.

There is another brand called Trailmaster. I have heard that TM is made by Zuumav, which sells the Templar line.

You might consider a liquid cooled 300cc bike to help control heat on slow rides on the trails. TM38 is one to look at.

Thanks Guys.

I ended up buying a '24 GPX FSE250E...air cooled with EFI.

In the big picture I am pretty pleased and the bike is decent for casual off road riding. Suspension is pretty harsh but hoping thinner fork oil and possibly softer springs will fix it.

The GPX is OK quality but IMO you need to know how to work on a bike before you purchase a GPX or a Kayo. My throttle cable broke due to the throttle stop no working correctly and my display is occasionally boing berserk. New throttle and cable from GPX for $22 shipping. Plan to play with the display and the sensor/magnet before I attempt to get a new one.

For $4,600 I feel my GPX was a pretty good bang for my buck even though it does and will require some tweaking and adjustment to get everything to the point where I am comfortable with it.

Good to hear you’re enjoying your FSE250e. Of all the GPX bikes, if I was going to purchase one, this would be the bike as the reviews of this bike on YouTube always sing it’s praises and for me, I need something that I can also make street legal and dual sport to get to the trails. Enjoy your new ride!

My 2024 GPX FSE250E does have goods and bads....

Bads:
A. Forks are very harsh over square edged bumps and all bumps at higher speeds. Low viscosity fork oil and/or softer springs might help.

B. EFI is super jerky coming off of an almost closed throttle...other than the jerk when you crack the throttle open, it works good. At this point, there is not a fix for the jerky fueling. A new ECU or reflash of the existing ECU will probably be required and there is absolutely nothing available, not even from GPX.

C. Only place you can buy OEM parts is from GPX in Salt Lake City, UT.

D. My throttle stop didn't work when my bike was brand new and the cable eventually broke. Got a new throttle/cable from GPX under warranty but had to pay $23 shipping to get the parts.

Goods:
A. Engine power...much better than I expected. The engine is the best part of the bike except for the EFI fueling jerkiness mentioned above.

B. Handling is pretty good.

C. Rear suspension is pretty good.

In the big picture, I think you get about what you pay for with this bike so you shouldn't expect everything to be perfect for $4,599
