What makes a Bridgestone different?
Before you buy a motorcycle, read about 12 important differences you get in a Bridgestone.
You'll discover why the people who ride Bridgestones say they are the most reliable and best performing motorcycles built in their price range.
You'll also learn why Bridgestone is today's biggest motorcycle value, and why it is now the fastest growing line of imported motorcycles in America.
Bridgestone engineering leadership
1. Bridgestone's leadership in original design begins on the drawing board ... long before a bolt is tightened or an engine tuned. Example: Bridgestone's new 175cc dual rotary valve engine, which Cycle World acclaims as "a design breakthrough in production motorcycles... that others will be obliged to follow."
2. Instead of conventional fuel induction, Bridgestone engines have rotary valves. That's one of the main reasons for the incredible acceleration of Bridgestone cycles. Most engineering experts agree that the rotary valve has brought the two-cycle engine its highest degree of efficiency and performance.
3. Bridgestone recently introduced motorcycle engines with aluminum alloy cylinders and hard-chromed bores, a Bridgestone exclusive. To you, this difference means better performance, substantially reduced maintenance for as long as you own your Bridgestone. And, Bridgestone engines are "clean" ... everything is enclosed, including the carburetor.
4. Bridgestone designed and built the first selective four-speed/five-speed motorcycle transmission for economical overdrive cruising at highway speeds. This transmission is standard equipment on every Bridgestone 175cc Dual Twin.
5. Three coats of paint protect every Bridgestone (that's more than many automobiles get today). Every steel part that isn't painted is triple-chromed. All aluminum castings are hand-buffed until they glisten. Result: A Bridgestone looks better when you buy it, and keeps its looks through all kinds of use.
6. There are quick-change rear sprockets on Bridgestone's two off-the-road motorcycles—the 90 Trail and 90 Mountain. This permits you to change them from 60-mph street machines to mountain-climbing trail cycles in minutes. Only Bridgestone has the quick-change rear sprocket.
7. Every Bridgestone engine is hand-assembled and inspected at each stage of assembly. Then, it's run on the stand to check performance. (We leave the final break-in for you, so your Bridgestone conforms to your particular way of driving.)
8. Bridgestones have special shock absorbers. As the wheels move up and down over a bump, the shock is absorbed first by a coil spring, then by an oil cushion, and finally by compressed air, which gives a smoother ride, without damping out the "feel" of the road.
9. Every Bridgestone is equipped with special tires to match its performance (at no extra cost to you). We can afford to do this because Bridgestone also is Japan's largest tire manufacturer.
10. Bridgestone's exclusive primary kick starting system eliminates the need to locate neutral before starting. (You won't really appreciate this Bridgestone difference until you have ridden a motorcycle without it.)
11. The brakes on every Bridgestone are bigger than they need to be. We even waterproof them to assure you safe, sure stops in any weather.
12. Every cycle goes through a 27-point check on a dynamometer before it leaves the factory. In addition, a completed cycle is periodically picked at random from production, ridden under the toughest conditions, and then torn down completely. Each part is inspected and measured for wear.
All this has one purpose—to assure you that the new Bridgestone you buy, like the thousands already built, meets Bridgestone's standard of excellence.
When you buy a Bridgestone, you have the satisfaction of knowing you own the best-engineered, highest performance production machine available in its displacement class. And, that's quite a difference, indeed.
