This is a bin of rubbish with GPI hoses sitting on top of the heap. This is where GPI hoses belong, not in your shopping cart or on the UPS truck.
Only one hose out four in the package came remotely close to fitting. The two inter-radiator connector hoses were different ID's, and neither was the correct ID for the radiator outlet barbs. One of these was nearly 1/8" off.
The water pump to right radiator hose was about 3" too short.
The cost of these hoses was around $20. I'd previously used these on a KLX300 and RM125, and both fit relatively well. If anyone with a 03-08 KX250 smoker knows of a kit that actually fits, lmk.

By comparison my dad bought Moto Hose for his CRF450 and they fit perfectly. More consistent wall thickness on his too.
What year are you putting them on?
The hose coming off of the top left side radiator was too long and the bends were a little off. I did my best to keep it from pinching where it entered the cylinder and i had to wedge it inside of the black support bar that extends from the radiator to the frame. I'm not impressed with the way it rest on the backside of the radiator fins but i was limited on what I could do.
The tube that extends from the water pump to under the pipe/kickstarter and then to the back of the cylinder had to be cut down multiple times from each end. The bends are also in the wrong spot and are off by over an inch when compared to the factory hoses. Due to the bends being off the tube rests on the backside of the exhaust. Its holding up well but is not the optimal setup for keeping coolant cool. I think i have 10-15 hours on the bike and they're holding up well.
Thinking about it, i think the hose clamps were goofy as well and i had to buy a clamp kit off of eBay.

The other two took awhile to figure out because one was bent and the angles didn’t work. The other which was the most difficult, (lower hose joining both radiators) had a funky bend. It took a few minutes of working it around, trimming, re-trimming to get it to fit just “OK”. They’re garbage. Never again.
Radiators fit perfect, only "odd" thing was the mounting tabs were thinner so i needed to replace the grommets that were on the OEM ones. Not a huge deal.
Hoses came with extra length, so i trimmed accordingly.
Met my expectations, especially for the cheap price of it all (~$140 for radiator and hoses).
If i recall correctly, i used their aluminum radiator on my FJ40 build ~8 years ago with no issues up until i sold the vehicle. Worked great rock crawling and kept the engine temps in check.
The only problems with the radiators is they came with a cap that is shallow so the stock ktm cap didn't fit. The ktm cap is too deep but the cap that came with hasn't had a problem. The second thing I didn't like with these is the cooling fins are way easier to bend and fold over whereas the ktms cooling fins are way stronger. You could pick them up by the fins and they won't bend. I told the ebay seller about those issues just so they would have feedback and they completely refunded me the full cost! Every penny and I didn't even ask for it! So that was cool.
The gpi hoses I recieved are still holding fine but it hasn't even been 50 hours yet. They fit up just fine for me. No bubbles in between layers or splitting/separating. Their 3 ply, and have a "warranty" too. Lol
If your not racing or using the bike in some professional manner I think these are fine alternative to spending $160+ on some damn dirt bikes coolant hoses.
