Yamaha seems to know what they are doing regarding marketing. There are Yamaha dealers every 100 or so miles throughout most of Latin America.. Much more prevalent than the other big names. Best dealer network there is. FWIW, the typical bike down here is a 125cc. Picture Mom & pop, with 2 kids aboard going to market or to church, and you now see the middle class. Honda, Suzuki, etc. all sell far more 125's than anything else. Pizza delivery, propane delivery, plumber's vehicle, you name it....the 125 is king, as are 50cc scooters. The Chinese Genesis brand has made huge inroads vs. the top 3, often selling like models at a 60% discount to the brand names. And yes, they sell. Right now, there is but one 250cc Yamaha available in all of Honduras, what with gas at $5/gal on my island and $4.50/gal on the mainland. Yes, VZ and Cuba have it a lot better.
On the other hand, for those that "have", the Yamaha cruiser bikes are popular, as are Ducatis, Harleys, Triumphs, Beemers and various other crotch rockets.. (Honda only chooses to market 125's) My 2014 S10, when it arrives in Dec/Jan, will be the 3rd one in this country.
Just a bit of insight.....
Safe Riding,
