Temperature in the 50's~60's is DEFINITELY well within normal operating temperature of the NSR, and if you need to tape up the radiator then there is something wrong with the system.

I've ridden my MC21, that makes 65~68hp depending on the conditions and setup, in all temperatures (including 45 mile blasts up and down the A30 in very low single figure temps) and it has NEVER needed the radiator to be taped up.

Make sure you are using the correct coolant and that the system is in tip-top condition. Average temperatures in Tokyo range from a low 34°F (1°C) to a high of 87°F (31°C) -- do you really think ANY major manufacturer is going to release a road-bike to market that cannot handle that temperature range without modification?
