defeat the final boss then go talk to tails. Tails will tell you the material's u need to get if you all ready have them he will upgrade it hope this helps
yeah you can upgrade the wave cyclone because i have already done it, you just beat the game and then you talk to tails. first you upgrade the waterbike, and then you can continue upgrading the rest of the vehicles. you have to get a lot of materials for each upgrade, so be ready to hunt materials! hope this has helped.

You have to drive a shipe that Tails built and find Johnny. Tails will ask you if you want to challenge Johnny in the Wave Cyclone. You're gonna have to sail out in the open to find him. If it seems impossible to beat him at certain races, have Tails upgrade the waterbike so it goes faster. Have fun people.QUESTION:How do you get to that part? I have completed the game and beaten the final boss with both characters, but there are no Chaos Emeralds showing on Sonic. I have all the Sol Emeralds for Blaze though. How do I get to the part you suggested above?-Pokefan1357ANSWER:All you do is you defeat the boss in big swell and then tails can upgrade your wave cyclone waterbike and then you can use the ocean tornado sailboat and then you just sail around randomly and when you find johnny the goal will appear before you planned it and tails will say a waterbike is coming this way at high speed! Then johnny will come and tails will ask you if you want to race him. The first and second time is easy, just win with your normal water bike then the third and fourth are harder and you have to upgrade your waterbike once and then you can win. the last two you will need to upgrade your waterbike three times then you can win.The first one you should have already in the story mode
