A recent thread about dirt bike pricing, got me thinking; are MX bikes prices rising faster than the rate of inflation? As the son of an economics professor (who first got me into dirt biking) and a past MX'er about to return to the fold I decided to do a little research. The last MX bike I bought new was a 1977 RM 250. I paid $1,600 OTD, which was top dollar (I bought the first one the dealer received). $1,600 1977 dollars, according to the Treasury department's numbers, is worth $4,787.39 in 2001 dollars (2002 numbers have not yet been published). A new RM250 will most likely run you around $5800 OTD (assuming a similar near top dollar price), which, when compared to the deal on my 1977, is about 18% more than the rate of inflation. So it would seem that the price of dirt bikes is climbing at a rate greater than the rate of inflation. We should consider, however, that the technology in today’s bikes is more sophisticated-- the bikes we can buy today are much closer to what the top pros are racing than those offered in 1977—so maybe a twenty percent increase is justified? No conclusions here, just food for thought.
