John McGuinness says he wants to "get on the podium at least" with the Norton on his Isle of Man TT return, following a two-year absence through injury.
McGuinness was forced to miss the last two TTs when he suffered a crash at the North West 200 in 2017 due to a mechanical issue with his Honda and badly broke his right leg, which he re-fractured prior to the '18 event.
The 23-time TT winner did race last year at the Classic TT in August - where he won the Senior race - and the Macau Grand Prix later in the year on a Paul Bird Ducati.
Speaking to Autosport during the 2019 TT launch event, McGuinness said he is now "back in my happy zone".
"I want to get on the podium at least," said McGuinness, who will race for Norton in the Superbike and Lightweight classes in 2019.
"The bike is definitely podium material. The win? [It] would be 'Hollywood' if we win. Anything can happen at the TT.
"I don't particularly think we're going to see those lap times again [Norton team-mate Peter Hickman set a new record 135.452mph lap in 2018], not unless it's absolutely perfect. They were just out of this world.
"But I've been around at 132.7mph, which would have got me on the podium last year. So we're in the hunt, anything can happen.
"I hate making predictions and stuff, because you come along all smart and saying you'll do this, that and the other thing, [then] karma gets a hold of you and you just look a dick."
While aiming for the rostrum, McGuinness admitted the most important achievement for him will be to "enjoy it and be safe", as he has "nothing to prove".
"In my own head I know what I want," he added.
"I want to be fast, and the most important thing for me - and it really is the most important thing - is to enjoy it and be safe.
"The rest of it falls into place however it's going to fall, but you have to enjoy it and be here for the right reasons.
"[I have] nothing to prove around here, I've done everything on every bike, all levels. So, enjoy it, fly the flag and just get stuck in.
"It's going to be tough. I think I can [get on the podium]. I've watched [Peter] Hickman's [record-breaking 135.452mph] onboard lap and I watched the sectors and all the bits and pieces.
"I need to nick a bit here, nick a bit there."
McGuinness is yet to secure machinery for the Supersport and Superstock races, but confirmed during the 2019 TT launch event he had been in talks with Michael Dunlop to run his MD Racing bikes.
