Okay...found an aftermarket dealer in Japan with sprockets for the Tricker. This one seemed be the closest to being useful (as in--made for the street rather than climbing trees) at 42 teeth.

Of course, the 'trick' (yes, pun intended) to a front sprocket, which is highly recommended to change for better street use (17 tooth is my recommendation, although I am not sure if the Magician/Hawk engine needs slight trimming to fit one, so you might be stuck with a 16) is to use the same one that the Hawk uses since the engine is Honda-based, NOT Yamaha. Those are cheap and plentiful all over the US on Ebay and Amazon.
This was the page from Webike which shows a few countersprockets (ignore those for the reason I mentioned) and a couple other rear sprockets which seem very expensive. The other reasonably priced 45 tooth states that something else is needed to work with the Tricker, so the 42 would probably do the 'trick' (couldn't resist
).
