Yamaha was celebrating 25 years of making cruisers, not 25 years of making the XS650. It's no different than Suzuki celebrating 40 years of selling bikes in the U.S., or H-D celebrating 100 years of making motorcycles.
So what? H-D is celebrating the anniversary of its first bike, which wasn't offered for sale to anyone (unlike Suzuki, which actually sold bikes in its first year in the US). Production bikes for sale from H-D didn't come until three years later, if my memory serves me correctly.
I was referring to grammatical nuggets like this one:
"In a short period of time, Suzuki established itself as one of the major brands in the rapidly expanding motorcycle marketplace, due to Suzuki's new model innovations, its response to customer needs and the reliability of its products."
Why can't they just replace the second "Suzuki" in that sentence with "it's"?
