Oil Cooler that would fit a 1970 Tiger #255597

Allo, Fellers, I'm thinkin bout installin an oil cooler on me ol '70 Tiger, 'cause on ol Rippington's highway runs the oil's gettin hotter than the frypan I cook me bacon in.

Any of you feller's know of a specific type/model of oil cooler that would fit discreetly, on the front down tube? I spose I'd mount a valve to manually turn it on for the days it's be helpin out with the sizzlin hot oil. Which vendor(s) sell the type of cooler that'd fit properly?

Ol' Rippington knows his 1970 Tiger runs a lot better on cool days than on hot ones, so based on that high tech assumption plus his scalding hot oil on them hot ones, he figures a good ol oil cooler might be a good idea, jus don't want to spoil the look of the bike, keep it discreet, ehh, good idea.

Appreciate suggestions for specific applications rather than fussin over whether or not is be necessary as ol Rippington's a stubborn ol codger an already made his ol mind up.

Thanks, fellers.

Please consider an oil filter instead for the following reasons...
It also acts as an oil cooler
It increases the oil supply, usually by about 1 pint
It will actually do something very useful year-round, that is, it will pay for itself

Hope this helps! bigt

(Sorry Richard)

I wouldn't have a Norman Hyde bog brush 'cooler' on my bike if I lived in Death Valley and there were no others!

Try Setrab USA:



I used the one on the left.



Fits neatly.

I once bought an oil cooler kit for a H*nd* XR600 some thing like the 3rd from left in Blaps post, still have it , it was designed for a dry sump engine so there should'nt be any flow restriction problems HTH jOHNNY.

Lockhart made an oil cooler specifically for British twins- I have one on both the TR65 and TR7T and they work excellently well !

Just FYI when developing the oil cooler on the Trident (I was Chief Applications Engineer for CovRad, who made the coolers) we did something very unusual and scientific for the UK auto industry at the time---we tried to find out how things worked.
One of the things we did was take a Trident into the full scale wind tunnel at MIRA (then known as Motor Industries Research Association) near Nuneaton in UK.
We attached small anemometers to the cooler and measured the airflow distribution across the face of the cooler.
You could actually measure much lower airflow behind the fork legs and behind the frame down tube.
The reason the Trident oil cooler sticks out a bit on each side is to get the edges into good airflow. We did experiment with a 6" length cooler rather than the 9" as fitted but the airflow was pretty bad.
This work was one of the reasons for the bog brush cooler designed for Norman Hyde---the cooler sees good airflow as it is not in line with the fork legs and is not obstructed by the frame down tubes.
So, sorry, Blap, your installation looks nice but the cooler is not doing as much for you as you might think.
Still, at normal bimbling speeds and not flat out all the time and at temperatures below about 30 deg C (86 deg F)then it doesnt matrter anyway.
Hope this bit of history helps.

Well I do like fettling, and hope to do quite a bit of bimbling so I'll check out all the above mentioned oil coolers. Meriden4ever, do you know of a vendor that sells the Lockhart one specially made for British twins? I did a serach and found that Lockhart coolers, but intended for Harleys, can be purchased with a thermostatic valve. I found that Setrab USA has an online store. Just gotta think of a good place to mount it where it gets max airflow, but doesn't look too outta place.

Hi Richard,

As my 8" cooler isn't as necessary as the 9" on the trident, I'm happy with it's location. I knew that it wouldn't get full air flow there when I fitted it there, but it is - as I said in my post above - neat. Putting it where it gets plastered and peppered behind the front tyre was never going to happen, neither was mounting it so low that it shielded the rocker boxes and head too much.

I read elsewhere that the OIF's low oil capacity is less than it should be and that the oil can run hotter than ideal so I thought I would help it. The bike was, of course, designed when fuel didn't cause the higher combustion chamber temps that modern fuel does...

Most of my bimbling (you got that dead right) will be done on hot sunny days and that is around 30C here.

I will be doing some measurements to see what temp the oil runs at when it's sorted. I can remove it entirely and revert to standard in a flash if necessary.

By far the best looking oil cooler I've ever seen on a bike was the factory one on my Royal Enfield Series II Interceptor. I'd like to find one lying around (the Bike or the cooler!)

I believe the 400,000 mile RT used a Trident oil cooler
