It is a 18 mm socket that works to get the spark plug out, it took me a while to figure it out.

the current model goes around 60 MPH
Honda quad models released in 2013 include the TRX 250X, the TRX 400X, the TRX 450R and the TRX 90X. 2013 Honda quad vehicles are available in sport, utility and youth models.
Intake and exhaust valves have the same clearance: 0.10 mm (0.0004 in).
i have a trx 250x, but i alternate tire sizes a lot, with the normal sized ones, i can get 60 mph out of it, then when i put the smaller tires on it, i can only get 52mph out of it, but as far as if everything were stock, id say close to 60mph..
Adjusting the valves isn't hard but it does take some knowledge of the subject. Check out my bio page for help.
on the rear axle housing, sprocket side, there should be a large spanner nut. Loosen the two bolts that tighten the rear axle in the housing and turn that spanner nut. Not sure which direction, you should be able to figure that out.
