Thanks guys, I'm having some wheels made up at Talon Engineering and the dealership is sourcing the exhaust so it should be about 6 weeks or so when I take delivery.

I think I'll run it in for 300-500 miles and then treat it to a new Vortex ecu...

Should be decent enough?
before you splash out on a vortex. ping me a message.
I'm working on a range of 4t ktm ecu tunes
 
Sorry guys I forgot to ask...
Once run in and I make changes to the bike, will it run just fine and more powerful with just the full Akrapovic/Vortex upgrade or do I need to do anything else?

Iv heard about desmog kit and airbox reed removal... What are your thoughts?
Has anybody done this?

Thanks in advance.
I think your reading into this too much, the reeds and desmog stuff tends to be US bikes. EU bikes should come ready to go straight from the dealer after PDI
 
I searched high and low to find someone in the UK (Pref South East) that can map a modern KTM but havn't found anyone - I can only find options in the US. I have a 2024 model 450 and only have an FMF can but was considering a header next, so def keen for a map!
well I also have a 24 450 which I've been tweaking the mapping for now for around 6 months
