Excessive heat from Thruxton R

I'm surprised at the amount of heat coming from my Thruxton R after an hour or so of use. Is this a design fault? It would appear that the bike needs a bigger rad!!

This is what the radiator is supposed to do: radiate engine heat and blow it onto your legs. What’s the temperature outside? It’s 90 F here. In the winter, I will appreciate that heat if the fan ever comes on.

Decat it with a xpipe and most of that heat goes away, it creates a lot of heat and it sits under the motor, I don't get hot legs at all now with my Meerkat and the bike runs so much cooler.

It is also hot here the low 80's. I'm not feeling it when i'm moving as most of the heat is dissipating before it reaches me. i can feel it when i'm stationary at the lights, it seems excessive. Even on fully faired bikes, i would feel heat from the engine but not like this and previous naked bikes wouldn't throw out this much.

Just found info on a Google search mentioning the xpipe also. Thanks for that Ashley

All good, my bike also has the fairing kit fitted and our summers are very hot, well 9 months of the year it is and the xpipe makes everything much cooler and your bike loves you for it, when I first brought my Thruxton and it was still summer it ran very hot as well my legs were cooking, but the xpipe fixed all that.

On the stock Rocket, the heat from the headers is barely bearable. With a full Jardine exhaust it was unbearable for me (Aussies are apparently tougher). I had to wrap those headers. I never noticed heat from the fan on the R3. On the T120, the fan blows directly onto your leg when you’re stopped.

+1 on the decat, takes the heat away from the bottom of the bike.

Is this your first motorcycle? My Thruxton R was one of the best motorcycle when it came to temperature...

Go try a Harley Softail or one of their Touring bikes... I had those and can tell you that those are by far the worse crotch burning hot motorcycles I have ridden...

The ThruxtonR was so comfortable riding in the summer here in Florida... So was my CBR600RR, but the Thruxton got that one beat when it came to comfort...

Ride safe!
