Supermoto on stock Stark Varg MX

[Erwin P]

Last saturday afternoon i decided i wanted to try a SM session. So i got myself a used leather suit from marketplace, put some road tyres around some KTM MX rims (21-19) i had lying around and had a blast the next morning.

Actually worked pretty well.
Was the only one to show up without proper 17' wheelset with slicks and one of the very few without tyre heaters.
Apart from the front brake getting a little squeezy over time and the grip when leaning in having it's limits it worked great. Well, i had a great time and that's what matters.

Would you guys go for a 3.50/5.00 or 3.50/3.50 SM rim set

Your setup reminds me of the Supemoto BigFoots that Gianni Borgiotti, an Italian supermoto rider, who used to be (still is?) almost pro level and still is an instructor, tried to spread years ago; he also competed in the S2 class (for the fastest amateurs and slower professionals) of the Italian Championship in 2014 with those wheels.
Here is a high level race he did like that during the motorcycles show EICMA:

I mean that the riders were high level, the asphalt section of the track not so much.
His idea was to use 19" with certain dirt track tyres, front and rear, to do supermoto and motocross and he said that they were cheaper than slicks, lasted longer and still provided quite some grip on asphalt.

EDIT: I've also found a video I recorded and edited myself during a race he did in a parking lot:
