Honda is a bigger company. Every lawnmower they sell keeps the price of your CBR down... FACT.
Oh and not to mention its like that across the range. For example the CBR1000RR undercuts the ZX-10R, as does the 600RR vs the ZX-6R...
that is true, with that kind of product line they can afford a loss now and gain later.
I wouldn't say that Honda's power equipment (or any of their other product lines) supports or subsidizes the CBR300R... every product a company manufactures has to stand on its own, both financially and in terms of profitability. In the case of a bike like the CBR300R (and its predecessor, the CBR250R) Honda makes a profit on these motorcycles by the sheer volume of units built and sold globally. While Honda's per unit profit may be relatively small on the 250R/300R bikes as compared to each CBR1000RR they sell, the total volume of 250R's & 300R's is what makes these small bikes so profitable. At the end of the day, Honda makes a lot more money on the small CBR's than they do on the 600 & 1000 CBR's. I'm just guessing, but I'll bet they have built and sold something like 50 or more CBR250R/RA's to every 1 CBR100RR over the past three model years. So even if the per unit net profit on the 250R is say $200, and the per unit profit on the 1000RR is $2000, it's easy to see where they will make a bigger overall profit margin. It's simple economies of scale.
Another aspect to all of this, is that these companies make a significant percentage of their yearly profits on sales of OEM replacement parts. This is true across all product lines. Using the CBR250R as an example, if you wanted to build this bike from the ground up, buying each individual OEM part including every last nut, bolt and screw, it would easily cost 3 to 4 times more than what the very same bike sells for at full retail price off the dealers sales floor. Why? Because that OEM replacement part which has a MSRP of $35 USD, likely cost less than $5 for Honda to manufacture (again, mass production & economies of scale). So, OEM replacement parts are a huge profit center for a company like Honda... you could say that the motorcycle (or car, lawnmower, watercraft, ATV, generator, etc.) is the
vehicle to sell OEM replacement parts.
While Honda Motor Co. LTD. is a huge, diverse company worldwide, so is Kawasaki Heavy Industries. KHI is the parent company of Kawasaki Motor Corp. KHI is a manufacturer of aircraft engines, off shore oil supertankers, robotics for mass production, underwater communication cable, heavy & light rail transit, to name just a few. In the bigger picture of KHI assets, the Kawasaki Motor Corp. division (motorcycles, watercraft, and ATV's) is a relatively small piece of the corporate pie, however it does stand on its own, and it makes money.
