Full fairing on Thruxton R

Just finished mounting a full fairing on my Thruxton R. I took the fairing constructed for my 2009 Thruxton and modified it a bit. I have a chin fairing about to ship and I hope to get it mounted soon.

The fairing is intended for me running out at Bonneville Salt Flats this year. The low bars and my old age will probably having me remove it for regular street duty.

I don't know which seat I will use for racing yet so I have pictures of both.

Thanks fellas...I had a couple of my crew came by and we took a few pictures with my leathers on and helmet to do a comparison on which appeared to most aerodynamic. The problem is finding a position I can hold for a minute and a half comfortably and aerodynamically .

To be honest we only peak occasionally to see where we are on the course which almost got me in 2016. The Corbin seat let's me slide back further but my neck angle is pretty bad so we decided to go with the stock seat and move up close to the wind screen. The only negative to doing this is having to relocate the Gopro so it is front of the instruments. I will miss seeing the tachometer on the Gopro since we make gearing decisions based on what see on the tachometer.

Good question. I actually had to remove the C clip on the bars to move them out some more. The rules require the bars be able to move from fork stop to fork stop without touching the fairing or gas tank. The bars are angled back towards the gas tank and clutch and brake controls are adjusted to miss the fairing. I'll add some pictures in a few minutes.

It looks to me if you were back against the seat hump, your helmet would be more out of the airstream as it is deflected up by the screen.
This may also help transfer more weight onto the rear tyre to help negate wheelspin.
But I do appreciate you are not as young (supple) as you used to be.

Yep it would be but like you said I can't crank my head up enough to see. However, the picture shows the relaxed position I will lower my head a couple inches for the last mile.

I did relocate the Gopro out of the way from this picture but this position has my legs out more. I will probably bring another helmet with greater visibility because I do prefer sliding back.

I think the hard part was just getting the courage to try since I knew it would try my limited patience. The brackets from the Triumph fairing were very useful and I tied on to the side covers for the lower fairing mounts. Clearance for the clip ons, front brake reservoir, headers, fork tubes, and engine safety lanyards meant making a few adjustments.

I am anxious to get my chin fairing in from Spain. Testing will be necessary to verify handling and identifying any resonance in the fairing. As you can imagine testing on public roads is a risky business and not something I want to do. The local drag strip will help but only up to 120 mph or so but if that works that might be enough and I can forgo any testing in public.

Right now the bike is geared with an 18/40 combination. I have nine gearing options.

Don't know if it would help you but a lot of racers at the IOM TT fit a little flip up on the screen for , I think , comfort and less wind blast its the sort of mod that you would be able to try then undo it if not successful . Looking at your on bike picture I'd also say you need tighter leathers cut in a more radical racing crouch . If you can walk in them they are too loose !

Thanks for the tip I never noticed them when watching on TV. I have two sets of leathers this one when I weigh 160 to 170 lbs and another set when I am 145 to 155 lbs. Today I am 158 and I'm shooting for 152 for August. I might pull the other set out and see how they feel, I see what you mean.

I had a set of made to measure leathers when I was younger and slimmer , the guy who owned the business displayed "used " leathers on his walls to demonstrate their effectiveness they were cut so tight that the medics had to skin them if the riders weren't able to get them off easily . Looked like somebody had been hunting racers .

Thanks but the OEM stuff is the best. When Triumph came around last year they said they had some full fairings that would fit the Thruxton R in a warehouse in Oregon and they would make it available to me. Alas nothing but crickets.

For street use you would probably want a taller upper section to accommodate more upright sitting position but for racing and short rides mine will work fine.

They look like a tighter fit , though in all honesty there are still some wrinkles on the arm and leg that the company who made mine would not be happy with . They aimed to have them fit like a second skin ( a young persons second skin ) . And looking at position on the bike you may benefit from a small flip up at the top of the wind screen .

You sir must be a police inspector, right on all counts.

The fairing was slightly modified from when I had it on my 2009 Thruxton.

I showed my seven year old grandson the bike before it was wrapped a he said " quite frankly grandaddy I'm not that impressed ".

I didn't want to ruin the red paint job in case I put it back on my old Thruxton, so I wrapped it.

I had Tamarit build the belly pan without the cutout to aid in aerodynamics.

P.s I got some reverse megaphones from Meerkat arriving any day now.

I have a 2023 Thruxton RS. The only stock fairing is the Dolphin. It doesn't offer much wind resistance. Does your design keep more wind off the rider? I'm worn out after riding 30 minutes without one. Shane
