The Ohlins DMX1222 rear shock is an Ohlins TTX Flow DV unit developed for Yamaha YZ 450F fitment. It uses a twin-tube damping layout to keep damping response consistent through repeated hard use. Designed as a tunable rear mono shock, it targets controlled traction and stability without relying on vague, over-soft settings.

Ohlins | Made to race, perfected to ride

TTX Flow DV technology is built around stable damping behaviour and clear feedback at the rear tyre. The internal architecture focuses on controlled oil flow and consistent pressure management to support predictable handling as conditions and pace change.

Shock design & features

  • TTX twin-tube construction
  • Oil and gas are separated (gas pressurised design)
  • Rear mono shock configuration for Yamaha YZ 450F applications

Tuning controls

This shock provides external adjustment for compression damping and rebound damping, allowing you to balance chassis attitude, bump control and drive traction to suit track conditions and rider preference.

Before you install

  • Spring is not supplied; select from the spring series noted for this shock
  • Ohlins notes indicate a preload adjuster that fits this model
  • This unit replaces the previous DMX 0221 application

Serviceability / lifecycle

As a serviceable Ohlins competition shock, routine maintenance is recommended to keep damping consistency and seal performance. Use the recommended Ohlins shock oil specified for the unit during servicing.

Need help choosing?

If you are confirming fitment, spring selection, or a baseline setup direction for your Yamaha YZ 450F, provide your riding level and typical track conditions so the correct combination can be selected from the available options.

Öhlins Motorcycle Suspension Warranty

New Öhlins motorcycle shock absorbers, front forks and cartridge kits supplied by Teknik Motorsport are covered by the applicable Öhlins manufacturer’s warranty against defects in materials and workmanship.

Teknik Motorsport is an authorised Öhlins Service Centre and administers warranty claims in accordance with the Öhlins warranty conditions. The service intervals below form part of the maintenance requirements for Öhlins products supplied and supported by Teknik Motorsport.

This warranty is in addition to the consumer guarantees that apply under the Australian Consumer Law.

  • Registered motorcycles — non-competition road use Five years, subject to correct application, installation, setup and servicing every: 20,000 km or two years, whichever occurs first.
  • Registered motorcycles — adventure and light off-road use Five years, subject to correct application, spring rate, setup and servicing every: 10,000 km or annually, whichever occurs first.
  • Unregistered or competition motorcycles Two years for eligible Öhlins MX and Enduro products, subject to inspection every ten hours and servicing every: 30 operating hours or annually, whichever occurs first.

Compliance with the applicable service interval is a condition of the Öhlins manufacturer’s warranty. Evidence of servicing may be required when a warranty claim is assessed.

A seal leak, loss of damping performance or internal wear arising after the prescribed service interval has been exceeded will be treated as a service or maintenance issue rather than a manufacturing defect.

Warranty repairs

Öhlins suspension products are designed to be serviced and repaired. Where a warranty claim is approved, the normal remedy is repair of the customer’s original suspension unit using genuine Öhlins replacement parts.

Replacement of a complete shock absorber, fork or cartridge kit is not automatic and would normally occur only where the product has suffered a manufacturing failure that cannot reasonably be repaired. This is at Ohlins discretion. 

Öhlins spare parts and service kits

Öhlins spare parts, seals, bushes, service kits, springs, fluids and individual components are covered only against defects present when supplied.

No fixed age-based warranty applies to wear items, service parts or consumable components. Wear, deterioration, contamination, incorrect installation and damage caused by another component are not manufacturing defects.

Öhlins gives the customer a meaningful five-year warranty on products (Units), provided the suspension is maintained as suspension should be maintained. Teknik supports that warranty locally, can inspect the product properly, and can repair it with genuine parts rather than discarding it.
