Hi everyone,
Thanks for the great information on this forum. I've learnt a lot since I found this forum.
I'm a newbie to motorcycles and just picked up a 2013 Thruxton about 3 weeks ago, and now looking into doing some simple mods my self.

So I've looked around the site, a lot of people have removed the Rear Fender & lights etc and fitted their own lights / indicators, and it all looks great! Naturally, I've started going down this path...

But I'm not able to find out what the effects (good or bad) after the removal of the fenders?
I've read somewhere (maybe here) that if you ride in the rain, you should leave the rear fender on. I don't ride in the rain (yet), and I understand kinda why you would want to leave it on, but HOW much of a massive of a difference is it if i take it off?
Will I be covered in back spray? Will people behind me not be able to see me at all cuz of the back spray?

Also, Dry or Wet ride, what mechanical problems arises from removing the fender? if any. Will the removal of the rear fender void the factory warranty by Triumph? Chances of stones back firing into the under frame?
Would be great to hear some experienced feed back by other rides who have already removed it, or WHY you decided not to. etc..

One last question (Just get it all in one thread)...

Anyone with experience with the K&N filter TB-9004 for 2013 Thruxton? Is it worth the minor upgrade? (not looking to change out the exhaust until the warranty runs out, so don't want to talk about the BC Airbox Eliminato... Yet).

Thanks in advance for the info people. ;)

First off, welcome to the forum. congrats on the new Thruxton.
I removed the rear fender about 5 months ago. mainly for the looks.
I'm so glad i finally got round to it. It improves the looks 10 fold in my opinion. As far as rain, sure your liable to get a bit wet but that is just something only you can decide. i don't tend to ride in the rain if i can help it. Also i'm here in California so i'm a bit spoiled compared to the UK were i use to live. As far as warranty issues i would give the dealer a call, but i can't see it should hurt as the fender kit protects the underside. i made my own it's pretty easy to do and rewarding.
I can't comment on K and N's on the efi model as i have Carbs. I can say the airbox removal and predators are great and put the biggest smile on my face:)
All the very Best John.

You will have the effect of having an infinitely better looking bike. Just make sure that you cover the now exposed electrics with some sort of cover. Most fender eliminator kits come with plastic squares with four bolt holes to replace where the fender covered the electrics.
As for riding in the rain, I didn't notice a huge difference. In a serious downpour, you are going to get soaked no matter what. In light to moderate rain, no serious issues.

Thanks for the replies so far.
Yeah, it does look great without the long wide fender... I know where to get all the parts, just gotta find out a bit more about it all.

RE: Cops... THAT i'm not sure about either tbh.
I'm going to head into the dealer and find out if they know.
I know there are a few cafe mod shops in Germany, just a bloody shame I dont speak fluent German.

I got stuck in a downpour (rare for San Diego!) a couple of weeks ago. I got soaked and had a little mud on my back, but it wasn't as bad as I thought it was going to be. Sometimes I notice some drops of water on my seat from going through puddles, but nothing that would make me put the stock fender back on. Weight savings and style points, any day!

I'm the odd one out. Ok I have a Thruxton with the shorter mudguard but I think the FEK look is just way too common. Besides as an all weather every day rider here in the UK a bit of extra rain protection is usefull:(:) I painted my scratched old silver fender matt black and with the rack on (i use a top case for touring or a stuff sack etc) you barely notice it. I have a freind with a Thruxton and no rear mudguard and her luggage gets soaked. Its nice to have dry pants to put on when you are piss wet through lol. I think it dependes what you use the bike for. TBH if its just a bar hopper then the FEK can look cool but its a very over done look in my opinion. The Mudguard can be shaped or trimmed and does keep yer smalls dry when on holiday. And my last wet holiday was a tour through Germany to Colditz and back via the Harz. ;)

Yeah, I have been looking into cutting the rear fender. Keeping some protection.
Right now, I've removed the stock indicators and installed a locus style brake light. Looks a lot cleaner, but rear fender sweeps down too much at the moment
Cutting and painting Matt black is a good idea. Maybe I can find a cheap fiberglass one to experiment.

If you decide to go without the fender (and are handy with sheet metal) I have created a template that you can print out and create your own.

From my experience, I've only had this fender eliminator for a couple of weeks and I love it. As others have said, this dramatically improves the look. I've driven through a small puddles and even a downpour. Both do not cause that much of a problem, it just kicks droplets of dirt onto the rear seat cowl (and obviously onto the new blockoff plate). Not too big a deal, just have to wipe off with a damp cloth.

Here's the link to the template

Also a short video showing the final product on my bike!

The look is improved, You loose about 15 lbs. you will get mud speckled on your back and rear cowl when riding in wet weather. Other than that no ill fate will come to your motorcycle. The only issue some people have is if they run pods with an open frame being no protection to the air intake without the fender. Most Airbox elimation kits come with a mud guard of sorts though or you could just mod your existing airbox. I Don't think you will appreciate any gains with the just the K&N. I'd read this.

I did a rear fender chop on my thunderbird sport a while back and it actually looked really good. Bought a simple lucas style tail light to shrink that ugly deal and some bullet indicators. I like the bobbed fender look too but it doesn't look as good as a gone one!

NB has a kit to remove the rear fender but they also sell the ABS shield separate. I didn't want the plate or light relocation part of the kit but for $29 I figured I'd give the ABS shield a try. Still waiting on delivery so I can't comment on how it works yet. Unfortunately by the time it does get here and I get it fitted there will be snow on the ground.

Here's a link to the part, it's located at the center of the page near the bottom:

I'm going down the path of Bobbed fender i think.
Looks a bit better (not as good as fender removed i know...) but still keeping some protection from dirt etc.
I wash my bike not so regularly, and find a lot of gunk and dirt under the fender as expected. So trading beauty for function is not a bad idea in my mind.

Does anyone have any photos of a good Bobbed or Cut fender Thruxton for reference?

Do it! Massive improvement in looks, slight weight savings, and unless you're going to be riding your bike in monsoonal weather, there's really no downside.
And go with the Maund kit - excellent quality, and one of the best people out there to deal with.

BC eliminator

Hi

I have recently bought a lot of bits (help me I'm addicted) for my Thruxton, BC stuff seems well if not better thought out than some other makers, and it coming with converters really helps.

Fender eliminator fits really well but I'm going to work to seal off the under seat area a little better as living in the UK I'm sure it will get wet.

Anyone else done this successfully?

Cheers
