That's yet to be built into it (work in progress) the Jack is a low profile jack two ton I got it specifically for this.
Maybe I missed it, but how high are you planning on lifting the bike?
Jus to be on the safe side, as it appears to be quite tall, I would do just a couple more things. You may already be planning on them, but...
I would add some diagonal cross bracing to the rear lift frame upright. As it does look to be quite tall, I would add possibly a front and rear cross legs/feet on the main lower frame for a bit of added stability side to side.
Just a suggestion.
Looking great non the less! Keep it going...
