Refinements and Replicas

The RM-Z450 offers balanced performance - st rong, controllable power delivery complemented by lightweight handling. The Suzuki RM-Z450 is loaded with advanced technology, including the Suzuki Advanced Sump System, the Suzuki Active Vent System, lightweight and durable titanium valves, hollow billet camshafts and much more.


  • New cylinder head with redesigned intake port shape for improved low-to-midrange power
  • Revised carburetor settings for improved low-to-midrange power
  • New piston oil control rings featuring chrome-nitride coating for improved sealing and reduced friction
  • Revised ignition mapping for increased power output especially at low-to-midrange rpm
  • Higher final drive ratio, (49/14 to 48/14), for easier power delivery control at all rpm
  • Reshaped shift fork guide pins for more positive feeling gear shifts
  • Relocated hot-start lever for easier access


  • Modified steering head pipe for improved frame rigidity
  • New swingarm with increased main beam diameter for improved traction and straight line stability
  • New f ront fork and rear shock settings for improved cornering and straight line performance
  • New rear brake caliper with higher rigidity for increased stopping power and better brake feel


  • Compact 450cc, 4-stroke, liquid-cooled, DOHC, 4-valve engine - lightweight design with emphasis on broad power delivery
  • Narrow cylinder head design featuring shim-under-bucket valve train with titanium valves for reduced reciprocating mass
  • Lightweight hollow-type camshafts with carburized surface treatment for durability and high lubrication qualities
  • Durable forged-aluminum piston with tin plating and oil retaining grooves to reduce friction and wear
  • Electro-plated aluminum cylinder bore for increased durability and heat transfer
  • Keihin TM FCR40 carburetor with hot start system and throttle-position sensor
  • Lightweight exhaust system with titanium head pipe with large-capacity stainless-steel secondary pipe and aluminum muffler
  • Automatic decompression system for easy kick starting
  • Suzuki Advanced Sump System permits low crankshaft placement for reduced engine height and low center-of-gravity
  • Suzuki Active Vent System - reduces crank chamber pressure and enhances piston ring seal performance
  • Four-speed transmission for weight reduction and compact engine size
  • Counterbalancer shaft gear-driven off the magneto rotor to reduce engine vibration without adding to engine size or weight


  • Attractive aluminum twin-spar frame designed for optimum strength, rigidity and weight
  • Aluminum swingarm with tapered beam design similar to RM250 - features cast-aluminum cross beam to improve straight-line performance
  • RM250-type rear suspension linkage - allows smooth movement of the rear shock and linkage for improved rear wheel traction
  • Lightweight chain guide design similar to RM125/250 - cutaway design reduces weight
  • Showa-brand cartridge-style f ront fork with 47mm inner tube, plus 22-way compression damping, 20-way rebound damping and 12.2 inches. of wheel travel
  • Showa-brand rear shock absorber with large 50mm piston and 18mm inner rod for increased oil flow and stable damping performance
  • Large 250mm f ront disc brake designed for reduced weight and high durability - includes Kevlar brake hose for low expansion rate and improved brake lever feel
  • Compact 240mm rear disc brake with lightweight caliper body similar to RM-Z250
  • New-style wheels, spokes and spoke nipples designed for the best balance of weight, rigidity and overall wheel strength
  • New-style f ront and rear wheel hubs designed for reduced weight and added strength - provides more rigid assembly when combined with larger axle, new spoke design and wide wheel bearing pitch
  • Specially-designed Bridgestone tires with large contact patch for improved traction and acceleration - 90/100-21 f ront, 120/90-19 rear - wider than competing models without weight increase
  • Renthal tapered aluminum handlebars with Renthal-labeled handlebar pad
