GPI Racing Radiators- Are They Good?

Recommended Posts

Yes. Very good. Many users here. Often slightly larger and finer fins, and they cool very well (better than OEM). Very inexpensive for what you get. Spend twice as much on Mikimoto if you want name brand and better welds, and they come with braced frames. Still not expensive compared to OEM. I have Mikimotos in the box but have not needed to swap out my GPIs because they work so well.

Ya and IMO from the ones bought, well made and worth the $$$$$.

They fit great on my 05 CRF250R (with a larger 250X tank) and the rads are larger them OEM so added a piece to the bottom of my Devol guards and use zip ties on the lower shroud mounts.

Before the bottom extension of the guards and showing a zip tie

I dont know if id call them stronger by any means, BUT. they definitely fit good, look good, and the price is amazing.   I have bought several sets and will continue to buy them.

 

but stronger than OEM.... I honestly dont think so.

 

rad guards are only $100 anyways.   you can get GPI and rad guards for under $200.    or you can get JUST the right side rad from the stealership for $300....

The thing that turns me off about them is the usually ugly welds.  But, I guess you can't expect an 8 year old kid in China to have mad welding skills.

Meh. These aren't a sema show bike. The welds aren't that bad. I've seen ugly welds hold, and pretty welds break. They're covered in mud most of the time anyways and tbh... We've got a few Hondas and a 17 Yamahas that have some disgusting welds on the frames too right from factory.

You'd be surprised about the 8 year olds though... Those boys got 5 years experience welding!!! They can lay a damn clean bead.

Yamaha welds are ATROCIOUS.

Oh man my gpi rads are taking an ass kicking. Still don’t leak though lol!! The branch that bit me yesterday almost broke my knee!! Bruised my LCL and tried to rip my rad open. Still rode with it like that all day.

Probably not flowing too well, though.

Ya sounds like you have bigger problems than the rad :(

Out of interest why are you not using guards/braces?

im cheap, and lazy.  usually dont destroy rads like this... but now that im on an enduro 2 stroke im exploring way crazier places, and have progressed a lot so I guess theyre mandatory for me now. it was a 4" diameter branch about 2' long, on a 45, rad height.  I hit it hard.  speared me and lifted the rear end. hurt my knee. bruised/hit my LCL hard in my knee and I had to stay at the hotel for my last day of riding Moab. cant put any weight on my leg at all. :'(

 

going to order another set of GPIs and some rad braces and go from there. oh, and header #3... im surprised I havnt wrecked my cylinder flange yet. thanks god for the trailtech flange brace.

 

flow seems to be fine.. ive got two temp gauges on the bike.trailtech TTO digital gauge and a tusk rad cap. both very close to each other, never went over or close to boiling.

I put gpi's on the Husky, and removed the guards ( F1 eng) as the gpi side plates are as thick as the gaurds are ( about double the thickness of the stock rads, and much thicker than the ktm ones above). So far they've handled a few landings on 'em without bending, the stock ones with the guards bent easy. Definitely stronger in this case.

They do seem to run cooler too.

Win-win.

They work but the welds looks like shit!, and its not super quality. But for the money they are good.

I would rather go with used OEM

Less capacity, less strength, and more expensive with OEM - yes even used.

+1, they are low quality, but work.  Used OEM can be had for the same price.  I have tried them on several different bikes, KTM, Honda and Yamaha.  1 set out of 5 actually fit without modification.  Look inside the rads, weld slag all over, and dirty right out of the box.  I recieved one set that had slag loose in the rad, part of the goober of extra weld had broke off, I bet that would be good for the engine.  I have tried to use them, but never again.  You get what you pay for.

Send them to Mylers, for close to the same price you can have yours fixed and braced as good as new. That way your money goes to a nice family business here, and their work is excellent and fast.   Or, you can send your money to China.  The choice is yours.

As a small local family business owner I know which way I would go.

You're an animal man.   I would never let you ride my bike. ;)

 

While you're enjoying Moab, this is the current situation here.

Mylers are double the price. I've only had one set of gpi for my KX. Exact fit.
