Ran them at 38/36 on the gravel and I found them amazingly sure footed. I was riding alot faster with them than the stockers. 40/38 on the blacktop. As others have noted, they are eager to lean into turns. I think the aggressive tread has more friction than the stockers and it slows the front wheel causing it to lay over. Pretty much used to it after a couple rides. Have yet to corner them hard but I did cruise up to about 105 indicated and the were smooth at speed. You can feel the blocks rumble a bit below 30 or so.
