Seems to me the volume increase in radiator capacity would require extra coolant, maybe good for keeping the engine cool, but extra weight in fluids... not sure if that's a good thing.

 

Weight? Talk about a non-issue on a piggy of a street bike.
a gallon of water weighs 8.33 lbs.
a gallon of ethylene glycol is 9.29lbs
So a gallon (128 fl oz) of 50/50 mix is 8.869lbs or 141.904 oz

Those aftermarket radiators MIGHT have 10~30 additional fluid oz over stock… but let’s guess in the wild side and say 60 fl oz. we are talking about the added weight of 66.518 oz just over 4 lbs
In other words nothing.
It’s not rotation mass on the motor or wheels, it is not unsprung mass that the suspension has to deal with.
Adding 4 lbs of sprung mass to a SH is about as inconsequential to “performance” as stopping for lunch along the ride.

 

Also that mass is fairly centralized, so it shouldn't really have that big of an impact really... But yeah, weight is weight... But I think the benefits outweight the potetial drawback on that one... As long as those radiators hold, and perform as they should...

 

I think the added weight is worth the extra cooling here in Arizona, and I doubt I'd even notice just street riding.

 

I have a hard time believing these would aid in cooling. Are you tying to increase cooling or just get less expensive units? Why not just ebay stockers?

 

I have Chinese "racing" radiators on my VTR.
Problems I encountered were:
Fan doesn't fit;
Fan switch doesn't fit;
Mounting brackets were not well located.
Fitting took some patience, time and beer. And a bit of grinding away of some of the fairings. Once on they have worked extremely well, no leaks and hardly need the fan unless stuck in traffic around town.
I got mine about a year ago off Aliexpress, maybe they have got better since?

 

Yes exactly what I have found as well. In the end you have new radiators, cheaper then you can buy new OEM.. But you have to deal with small mods to make them fit.

Never tracked and compared temp data to know if they cool better than serviceable OEM ones, and not tried a pair on the VTR yet.... so take info with that note.

 

Sorry to drag up an old thread but ive been considering these for quite some time now.. as im running my bike naked right now the fitment of the fan is a non issue and i have no fairings to mind...

But what do you guys mean the switch doesnt fit? Hits the fairings, wrong threads....?

 

The bike that I am parting out came with a larger chinese radiator mounted on the right side, a good stocker on the left side and an unused chinese left in the spare parts box.

The bung for the switch was plugged with a bolt on the right side chinese radiator. The left Chinese radiator doesn't have a bung for the switch.

I think the switch goes on the oem left rad. So that might be the issue. When I get home tonite I will check and confirm what the actual issue is. IF it's a matter of switch being on the srong side, then just splicing in some wire to extend the sensor leads should solve it.

The chinese rads look home/hand made compared to the OEM and is quite a bit larger.

 

Yea wiring is a non issue... if noones claimed those yet how much do you want for them and can you take pictures if you havent already?

Thanks

 

They radiators have not been claimed.
Here's the pricing:
Radiator, OEM , left side, undamaged: $50+ shipping

Radiator, aftermarket, pair, undamaged, left side is unused: $70( left and right) + shipping- these are Chinese I believe.

The chinese right side mounted on the bike. see the plug in the left upper corner for the temp switch.


Chinese left and right:


stock left


The switch position is the same on both the stock and the chinese. So the switch incompatibility issue has to be investigated. I will remove the plug from the Chinese rad and see if it fits the stock radiator. If it does fit, then there is no fitment issue.

 

I would definitely want these but i need to wait til i get paid on friday to confirm that... if you can give me dibs on them i would appreciate that but i understand if youd rather get rid of them when a serious buyer comes along. Let me know

 

I will hold them for you for a week. no problem.
