Our engine parts category at Hornig offers a wide selection of high-quality components specifically for classic R80 boxers — from indispensable wear parts to robust maintenance and replacement parts. This ensures your engine remains reliable, durable and technically sound.
The timing chain is the heart of the valve drive: at Hornig you will find both the duplex timing chain with master link and the simplex timing chain with master link — both variants compatible with all R80 boxers.
In addition, matching chain tensioners and guide rails for simplex tensioners are available to correctly tension the chain and ensure a safe, quiet running behavior of the engine.
For the valve train there are stainless steel pushrod protection tubes (in 18 mm and 16 mm) — these protect the pushrods from wear and corrosion and are especially recommended for high mileage or long periods of storage.
As wear protection and to preserve engine performance, Hornig also offers piston ring sets (per piston) — essential when the engine has been heavily used or a rebuild is performed.
Whether you are planning a complete engine overhaul or just want to replace wear parts — with Hornig’s engine parts you cover cylinder base, cylinder head or valve train work as well as simple repairs. The use of high-quality materials and precise manufacturing guarantees long service life.
With Hornig you get parts that are specifically matched to the geometry and requirements of the R80 boxers. Our engine parts combine precise fit, material quality and durability — ideal for maintenance, repair or preserving the performance of classic boxers. This keeps your machine reliable, powerful and safe.
When mileage increases or after many kilometers, plan a thorough inspection: timing chain, chain tensioner, pushrod protection tubes and piston rings should be on the checklist. Targeted replacement prevents wear, uneven compression or engine damage — and extends the life of your boxer.
With the extensive engine parts range from Hornig — from timing chains to chain tensioners and pushrod protection to piston rings and maintenance components — you equip your BMW R80G/S, R80ST, R80, R80RT, R80GS or R80R optimally. This secures performance, reliability and longevity — whether for everyday use, touring or restoration.
