Hitting the open road on your 1977 Yamaha RD400 means freedom, exhilaration and an escape from the daily grind.
But never leave your garage unprepared. Keep your motorcycle in tip-top shape by performing some basic maintenance - replace worn spark plugs and the clutch kit for a no-bog, instant response ride. The engine in your 1977 Yamaha RD400 loves fresh oil and at MotoSport we stock a variety of oil and other lubricants from the industry's most trusted manufacturers. Working on your street bike takes a good set of tools and we carry all the specialty tools you'll need to get the job done right.
Additionally, make sure you check your tires for wear and proper tire pressure before heading out. If the tires on your motorcycle have seen better days, a fresh pair makes an extremely wise investment. At MotoSport, find the right motorcycle tires for your 1977 Yamaha RD400. Finally, keep your street bike's wheel bearings in prime condition to ensure a smooth ride.
Forget the master technician secrets and take your 1977 Yamaha RD400 to the next level of performance with our wide selection of bolt-on and slip-on exhaust systems. Simple exhaust upgrades often unveil a street bike's true horsepower potential. If you want to upgrade with a full exhaust system - and really bring out the power and weight savings - then we've got that for you, too.
After you open the exhaust and added a roaring sound, let her breath a bit with a performance-minded air filter like K & N Air Filters or BMC Air Filters. Once you have installed all this new hardware fine tune the power with a fuel management system. A fuel management system gives you the ability to adjust the air/fuel mixture that feeds your motorcycle. Most of our fuel management systems provide you the option of self-tuning to accommodate different riding styles from racing to high mountain cruising.
