The Ohlins BM345 TTX GP rear shock is a dedicated rear mono shock for the BMW S 1000 R, developed from Ohlins race suspension architecture. It is built around consistent damping control and clear chassis feedback when riding at higher loads. This unit uses a separated oil and gas design to help maintain stable damping through longer sessions.

Ohlins | Made to race, perfected to ride

TTX GP sits at the sharp end of the Ohlins road-and-track range, focusing on predictable response and adjustment range rather than comfort-focused compromise. It is intended for riders who want to tune chassis balance accurately and repeatably.

Who this shock is for

Suited to riders using the BMW S 1000 R for trackdays, fast road riding, or competition where traction and stability matter most. It is also a good match if you already understand sag and damping changes and want suspension that responds clearly to adjustments.

Shock design & features

This is an Ohlins TTX GP rear mono shock using a separated oil and gas layout to improve consistency. The damping architecture is designed to give stable support under braking and acceleration while maintaining tyre contact over surface changes.

Tuning controls

The BM345 provides external damping adjustment for both rebound and compression, allowing you to tailor behaviour for different tyres, surfaces, and riding styles. It also includes ride height adjustment to help fine-tune chassis geometry and weight transfer.

Before you install

Set sag first, then make damping changes one at a time so you can feel cause and effect. If your bike has been modified for weight, tyres, or regular track use, confirm the spring choice and baseline settings during installation.

Serviceability/lifecycle

Like all high-performance Ohlins shocks, the BM345 is designed to be serviced to restore damping performance and seal integrity over time. Regular servicing helps maintain consistent feel and protects internal components, particularly when used on track.

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.
