5 mil JPY is about 60,000USD right now, give or take. For the time, NR was more expensive, close to 100K in today's money, and they're going for over 100K used today.
So, all these considered, its a bargain. Honda is getting more economically minded. The 2013 CRF450R is the first new motocrosser they have EVER released that was not more expensive than its predecessor.
After 5 years of averaging 85:1 JPY/USD exchange rate in their largest market, they are finally starting to figure out that they need to make up for that 15% somehow. Suzuki learned the hard way.
