What about the KTM 690 SMC R?

That’s a road bike, bigger and heavier.
Not a race bike.
The 450 SMR comes with slicks on it [emoji106]

I chucked the Akra exhaust on it and that's it, so god damn good. The only thing that is weird is air forks, but I refuse to drop 4k on ÖHLINS for a SM

Whatever you do, try to resist the temptation of an SXV 550. 74 hp world's smallest production v-twin class killer from back in the day. Everyone will tell you not to do it, and everyone is right!
God I miss that bike. I set some fast times and walked some fast people on their fast motards. My wife and I even did a back-back trackday on it both of us riding it in different groups! All was right in the world right up to free practice on race day when it spectacularly exploded on the straight, dumped oil and caused 4 racers behind me to crash out of the weekend. Bad karma. Only two guys in the USA who can rebuild the engine (one of them in SoCal....)
Get the KTM 450 lol

She’s loud….started it up today to purge the cooling system….Also Jimmy made an elegant solution for two O2 sensors we are running, front bank and rear bank….mounted the plugins for the O2 sensors right next to each other under the left fairing using a CF bracket he came up with….so when we are street/track logging we can simply plug in the front bank for a session then the rear bank for the next session and get both banks individually tuned.

some Karen’s are going to have ruined days with that exhaust….luckily most of the people in my neighborhood are gearheads and tolerate our noise lol

Keep in mind that the unpowered o2 sensors are going to get contaminated because they aren’t being pre heated by the controller.
There’s varying opinions on the subject… some say an unpowered sensor will .... it’s self if left plugged in the exhaust, others say it will at least need to be cleaned and recalibrated.
What o2 controller are you using?
Why not wire in another one to control the other 2 sensors?

Put me in the camp that says the heat from the exhaust is much greater than what is generated by its own heat.

The fouling occurs during startup from cold. Sensor has condensation on it that erodes the sensor if it isn’t burned fast enough.
Same goes for exhaust contaminants and rich fuel mixture.
It needs to burn off fast to protect the element.

we are setting everything up on the Woolich System, Woolich will let you tune cylinder by cylinder or by banks or all at once, BUT, it can only read one O2 sensor, so you have to move the O2 sensor cylinder to cylinder to do cylinder to cylinder tuning.
I don’t want to have to do that while doing street or track tuning so the compromise was to put one O2 up front and one in the rear banks, both in the easiest to access location should we have to clean or replace them, we then ran the lines to that place under the left fairing so I just have to undo a couple of Dsus fasteners and move the plug an inch over to switch from rear bank to front bank tuning.
we also routed the man logging port and the data logger up near the battery and will mount it for easy access instead of it running past the engine and up under the seat in the rear subframe.
as an aside, we eliminated the entire smog system and blocked off the SIS or whatever it’s called so no extra yucky stuff will be recycled through the exhaust system, that should help keep those O2 sensors from getting fouled, there will be less gunk to burn off.

we chose the two O2 sensors that grant easiest access, and once tuned we won’t have to retune that often….but I’ll have the option to if for example we find ourselves at a track day where the DA is unusually high on a really hot day etc
so pulling them to inspect or clean won’t be too difficult
