Nice trike, nice and open easy to work on if need be. Few other folks have that model maybe they will chime in.

I have one (purchased last July).
It's a fun little trike, people are constantly asking me about it. If you are the shy type this is not for you.
Be aware that, as with all Chinese scoots, it will not be perfect when you get it. Even if you pay for PDI.
There will be (mostly minor) adjustments & repairs to be done. If you feel comfortable tinkering with mechanical things, you can handle these yourself. It's imperative that you buy from a reputable dealer as he/she will be your "representative" to the factory (in this case Ice Bear) regarding any warranty claims. Personally, I highly recommend Jim from Rapid Repair. He was superb in helping me resolve any issues I had with the Viking.
Riding the trike takes a little getting used to, but once you feel comfortable on it, it's a hoot.
Top speed on the Viking 150 is around an actual 50mph at 6800rpm with a normal sized rider. It launches briskly and steadily pulls to 45 or so, then takes an extra few seconds to eke out top-end. Note that I made a few bolt-on modifications to mine when new (see sig) so don't know if a stock one performs the same way. I don't check mpg but would guess I'm getting 55-60 with mostly city riding.
Hope this helps!

Yes you can get it to go little faster without going overboard and not at wide open throttle. You can do it yourself if your somewhat of a mechanic or have the trike delivered to JIM and he can do it for you so when it gets delivered or you pick it up(DEPENDING ON WHERE YOU LIVE THAT IS) it will be tested and ready to ride.

The tires alone will make a big difference, with the current 205-50-10 and putting on 205-65-10 the difference is 2 1/2 taller tires. With taller tires the faster you go the more you gain, at 30 the difference will be about 3 mph at 40 about 4 mph at 50 about 5mph. Also you will need LESS rpms to cruise at a given speed over the smaller tires.

Then you can put on a 115mm performance Variator to create a bigger wheel turning a smaller wheel(the Belt Down in the Clutch Pulley) for a few more mph as well. Then finally you can put in Taller Gears to even get some more top end speed(but this may require more power to the motor) it all depends on the motors Low End Torque some motors produce more hp than others.

But this should give you I think what your looking for a gain in top end anywhere from 5-8 mph without going into the motor. It should run REAL 55+mph with no sweat, the speedo might show in the 60s but they are way off and more so at higher speeds.

Gotsa question.
Are there any front-end adjustments necessary (other than headlights) to compensate for the rake from larger diameter rear tires? Handling affected at all?
