Large diameter front forks nowfeature variable damping controland sturdy integral fork brace foreven better front end stability.

New "powerfender"design'saerodynamic shape emphasizesclose relationship to RZ500.

Improved swing arm designincorporates full length box sectiontubing for increased strength andneedle bearing pivot for optimumcompliance.

6-speed close-ratio transmissionto make the most of the RZ'sincredible engine.

Yamaha's Power Valve System. Micro-processor controlled for maximumhigh speed power output togetherwith maximum midrange torque.

Slotted double disc front brakes nowutilize opposed piston calipers formaximized braking efficiency.

50° liquid-cooled 499cc V-4 two-strokedelivers unmatched power for its class.The twin crank engine design houses side-mounted 4 x 26mm Mikuni carburetorsand uses Y.P. V.S. to carry its exhilaratingpower band over the widest r.p. m. rangepossible.Race-bred to lead the pack, the RZ500engine is the ultimate production 2-strokewith durability built into the overall design.A more sophisticated autolube system islinked to the Y.P. V.S. servo-motor ratherthan the throttle to exactly meter oil injec-tion to exact engine r.p.m. 's even duringhard decelleration.

Large faced, fairing mounted instrumentsfeature a central electronic tachometer togive performance information in a glance.

The illustrious track record of the RZ350begins with the proven performance of its374cc two-stroke twin.Liquid-cooled for even running withmaximum durability, the RZ350 engineis famous for going longer and strongerthan competition twice its size.The Yamaha Power Valve System raisesand lowers exhaust port timing in accord-ance with engine r.p.m. 's to deliver ulti-mate high speed power without sacrificingmidrange torque.With features like 6-speed transmissionand C.D.I, ignition, the RZ-350 is asstreet-wise as it is track ready.

Square section steel frame employs a wide-ly spaced double cradle design with heftybracing at the steering head and swingarm pivot. The lower right frame sectionremoves to allow easy engine access.

Decarbon-type single shock mounts hori-zontally beneath the motor to keep centreof gravity as low and as central as possible.Forged alloy linkage provides rising rateproperties with 120mm of travel adjusta-ble for preload and damping.

The rising-rate monocross suspensionprovides the right progressive action forvaried surfaces and riding usage.5 way adjustment is possible by simplyturning the remote control adjuster. Thelightweight monocross suspension systemworks together with the new square sectionswing arm to give the most positive rearwheel tracking ever.

Front dual disc brakes employ opposedpiston calipers for 1985, as does the singlerear disc brake. These high efficiencycalipers give even better braking perfor-mance than ever before.

If you want more bike,you'll need a track to ride it on.

Until now, you had to ride fora living to ride bikes like these.The RZ500 and the RZ350 arevirtually grand prix racers madelegal for street use. They are themost uncompromising perfor-mance motorcycles ever offeredto the public.

Yet, while their full potentialobviously can't be realized excepton a track, their precise handling,braking and superb road-holdingmake them the ultimate streetbikes for experienced riders.

The RZ500 flies at yourcommand through a rocket-likeV-4 liquid cooled 2-stroke withawesome horsepower and torquein very compact dimensions.

Its close-ratio six-speed trans-mission is derived from Yamaha'schampionship road racers forlight, quick responsive action.Brakes are the same triple, ven-tilated disc type first developedfor Formula One race cars.

The RZ's 500's suspension,fairing and frame geometry addup to a low, central centre of

gravity, great strength and rigid-ity and very stable, predictablehandling.

Like its bigger brother, theRZ350 features Yamaha's PowerValve System, the incrediblepatented power-booster that'sblasted it right out of its class.The thrust you feel from 7,000through ll,000rpm will makeyou think of bikes twice the size.

But it comers like somethingelse.

Wide-spaced frame tubesand rigid triangulation make for

impeccable handling that's fur-ther enhanced by light Monocrossrear suspension and ultra-positivedual front, single rear brakes. Aslim chassis design permits leancornering angles of near 50°.

TheRZ500andtheRZ350are built to show the competitionno pity on the track, but theyperform with the best of mannersaround town.

If you want to see what theother guys are doing in the faceof all this, it's easy.

Just look over your shoulder.
