The 400 frame is at least as stiff as the OE 1135 frame - possibly more so. Some judicious bracing will help.
Any extra grip from modern rubber is moot as these things become rear wheel steerers in the hands of a decent rider anyway - which "proper race bikes" of the era wouldn't readily do.
They have enough surplus HP to carry sideways action for as far as the rider wishes...controllably.
I love 'em.

Yeah right.. Kanemoto & Carruthers thought otherwise..

& actually, could it be why the AMA banned them - to stop them - from doing just that?

I always thought the AMA banned it because the Hardleys couldn't keep up...also pretty sure Kenny Roberts recommended it be banned.

AFAIR, for Kenny, it was more like "I don't get paid enough - to ride this thing"..

He got a contra-deal from the AMA, whereby roadracing was to be separated from dirt, championship-wise,
& so he went to Europe & took back the 500 G.P. class crown for Yamaha ( X3) from Suzuki/Sheene...

Kanemoto went F750 World-Championship hunting with Gary Nixon & the Kawasaki KR 750/3, but got stiffed for the title...

Erv Kanemoto, as noted - did it with that H2R, before the TZ,
& factory F750 Triumph/BSA triples were used on the mile dirt tracks, before that too..

Here's Gary Nixon doin' it on the dirt..

**Hemi Makutu** · 28th October 2016, 12:14

Here he leads the Sacramento mile on a Triumph triple.

Nixon, Don Emde, Romero.

No one ever won a major dirt race with a factory trident. Nixon got closest but fell when he grounded the cases which was the main problem with them.

This is not relevant to building a post classic roadrace special.

If the rather wide crankcases of the big Suzuki 4 stick out further than a 400/4 - in the same chassis?

& the discussion was in relation to sliding about on big roadrace engine powered bikes back in the day.
Both the H2R & TZ 750 did win on the dirt, wide cases 'n' all- if maybe set a bit higher - due to no bulky/heavy/complex 4T top-end..

AFAIR, 'On Any Sunday' shows Jim Rice ( or was it Dave Aldana) tossing his BSA Rocket 3 dirt machine away,
- after winning a Q-'heat' race for a 'major', the Sacramento mile..

( & those three factory Triumph riders do have their first names clearly visible on their trick white leathers).
