Details

    FMF's Gold Series Fatty Moto is one of their most popular pipes because it provides a smooth power band, increases in power all along the curve, and better control regardless of where you are in the power band.

    Unusable peaks in power will be leveled out and more power in the lows and mids will be added. The top end doesn't suffer since all the original punch is maintained along with more over-rev. That means more fun all around no matter the type of riding you like.

    Why? Because with more usable power you get a better hook up during acceleration and more control while you ride aggressively on dicey terrain.

    And with FMF using their Tru-Flo stamping process and signature nickel plated finish, contours are consistent and corrosion is kept at bay throughout the header pipe's steel body.

    Specs:
  • Improved power throughout band
  • Increased over-rev
  • Smooth power delivery
  • Carbon steel body with nickel plating prevents corrosion
  • Tru-Flo stamping process ensures proper contours and fitment
  • Most models include new O-rings
  • Made 100% in the USA

Turned a ktm 65 buzzsaw into a 2 stroke monster!
The stock ktm 65 pipe sounded a whole lot t
like the 50 my boy got off of. The new pipe made it sound like a true 2 stroke.

This is a tried and true pipe....among the very best. Make sure to buy the appropriate jets when you buy the pipe.

Have ran these pipes for 10 years
FMF always delivers performance as advertised. Holds up to abuse reasonably well, much better than the stock pipe.

Great performance and fit
The FMF Fatty pipe delivers as advertised. My only complaint is I would think by now they've already recovered their development and tooling costs for a 2002 bike and could afford to offer a little price break.

Awesome pipe
Restoring a 1997 WR250 for vintage racing. Response is excellent. Quality is great. The 4 for fitment is probably a function of a 20 year old frame. As usual, service from Rocky Mt is exceptional.

Looking for more mid to upper power for deep sand. This pipe delivers without sacrificing low end.

I wanted a gnarly for the thicker metal, but the big bore kit I installed was built around the fatty pipe. I put on a cheap tusk pipe protector and it's holding up very well, although from the pipe protector holding the dirt and mud in, the pipe rusted really quickly. So now it looks like crap but performs just as well.

Generally awesome pipe.
The pipe arrived very quickly and almost slid right onto my 95 Yamaha WR250. Everything lined up except that i had to make a small dent in the back of the pipe to let it slip past the screw-head on the power valve cover, maybe a 5 minute installation.
Power-wise was very pleased with the bottom end torque and the a smooth power curve towards the top end. A good all around pipe that does wear you out like a dedicated track pipe.
Finish and and build is beautiful as with everything by FMF. I definitely recommend this pipe and will never go back to stock.

Is the best exuast for the 2016 kx85 the fatty pipe along with the shorty silencer ?
A shopper on Sep 1, 2016
BEST ANSWER: Regarding KX85 Fatty (yes, I would recommend the more general Fatty over the Narley). However this also depends on your riding environment (woods or MX and overall needs). If you want more top end (Speed) then consider other, but for general broad improvement mostly bottom to mid range the Fatty is golden, without compromising additional weight. If you want additional durability & slightly more weight than the thicker metal Narley is a comparable solution to the Fatty. Shorty sliencer is icing on the top. Sweet combination!
Dose it come with springs and o rings???
tomi v on Feb 14, 2017
BEST ANSWER: Does not come with springs and I cannot remember if it comes with new orings but I would order them just to be safe. Definitely no springs were included.
Does this come with new springs and o rings?
A shopper on Feb 9, 2017
BEST ANSWER: I'm pretty sure the pipe came with a new o-ring but the springs were not included. If you call customer service they are awesome to answer any questions. If anything doesn't work they'll make it right. Best company I've ever dealt with for parts. The local shops can't get your parts as quick.
im looking for a pipe with the best top end. which do you perfer? i run a cr250r on a racing flat track kart. completely different than how it runs on a bike. thanks!
A shopper on Aug 8, 2017
BEST ANSWER: I bought this pipe for a 2013 xc KTM. I had a black pro circuit that came from a racer friend. If you can find a pro C I would try that for the top end. I know apples and oranges but it was a world of difference for me.
how many powerbands will this add?
cody l on Nov 24, 2017
BEST ANSWER: pretty sure it added at least 2 to my 2000 pw50. great quality product.
What is with the FMF Gold Series Pipe, "Fatty Moto"
Fits: 2006 YAMAHA YZ125
Part# 1087090099?

There is nothing on FMF website that refers to it as "FMF Gold Series Pipe, "Fatty Moto". Why can't we see the mfr part # to match and know what we are buying?
Derek C on Mar 9, 2017
BEST ANSWER: Their manufacturer part number is 024049. On their website it is just called Fatty under the two stroke pipes.
