KTM 640 Adventure LC4 Akrapovic Exhaust Installation and Comparison

The KTM 640 Adv has rally heritage and is a future classic. With that said, I recently installed an Akrapovic silencer on my KTM 640 Adv, and provided a comparison to the stock Supertrapp silencer. The bike finally sounds like a rally bike instead of a paint can! Hope you enjoy!
KTM 640 Adv Akrapovic silencer part number: 57305079400. Can be found for ~$625 or so.
As for the 950 build, I am still working on it. What was initially planned to just be an OEM restoration build has transitioned into a full on rally build incorporating KTM Rallye parts, along with numerous custom one-off parts. I will provide a video update shortly and greatly appreciate your patience!

Just picked up a creampuff hyperminty 05 640 ADV with 4k on the clock. Only has the center stand. Any idea where a brotha could slurp up a side stand for her? Tryna keep chazz levels stable while on trail not put her ass up every blaze sesh. Cheers.

[@tomvivash]

[@michaelkrumrine1144]

Did you change the main jet or was it happy with the stock jet?

[@bivouacmoto6440]

I upgraded to a 162.5 main jet.

[@_mk7080]

hi, does the engine of this bike need a lot of maintenance? thanks

[@Angry-Lynx]

no

[@mathieuledemidieu9221]

Did you adjust the carburator ?

[@ashwilliams4989]

This Akrapovic muffler for the LC4 640 is tuned to the stock settings of a Mikuni BST 40 carburetor with a 157.5 main jet (p/n 584.31.023.157) and a Keihin FCR 41 MX with a 188 main jet (p/n 545.31.623.188).
