BMW R 80 G/S classic bikes for sale

Introduction and history of BMW R 80 G/S

BMW launched the R 80 G/S in September 1980 in Avignon, with a development period of just 20 months. As the first true large-capacity enduro, the R 80 G/S bridged the gap between reliable road bikes and agile off-roaders, paving the way for the adventure bike category. With a focus on everyday usability, the R 80 G/S excelled in everything from regular commuting to taxing rally events like the Paris Dakar. The robust construction, low-maintenance shaft drive, and long-distance comfort cemented its reputation throughout the 1980s.

Model history

The R 80 G/S was developed as an evolution from BMW’s road-oriented R 80/7, sharing much of the engine architecture but gaining innovative features for off-road riding, such as the 'Monolever' single-sided swingarm with an integrated shaft drive. Production ran until 1985, with sales continuing into 1986. The concluding series appeared in 1986. It later gave rise to further influential models in the GS (Gelände/Straße) family, maintaining its DNA in later BMW adventure bikes. The R 80 G/S itself succeeded no previous GS model, but it became the forefather of all BMW GS-series motorcycles.

Highlights of the BMW R 80 G/S

The R 80 G/S stands out for its blend of road and off-road performance. With a lightweight, steel double-loop frame and the innovative Monolever rear suspension, rear wheel changes became much easier compared to previous designs. The high, comfortable seating position, ample ground clearance, and robust 797cc air-cooled boxer twin made it ideal for tackling both tarmac and rugged terrain. Specifically, the original 21-inch front wheel, long-range 31.4-litre optional fuel tank, and carefully balanced chassis enabled reliable long-distance and rally usage.

Technical data

Special Editions and Collectible Models

The most distinguished R 80 G/S special edition is the Paris Dakar variant. It is instantly recognisable due to its 32-litre fuel tank, which often featured a signature by Gaston Rahier, and unique graphics. This version was tailored for extreme rally conditions, offering increased range and tougher ergonomics. Another rare feature is the original kickstarter, which was available as an option.

Weak Spots and Common Issues

Areas to check on the R 80 G/S include rust at the centre stand, mirrors, and especially the front silencer. The steel tube frame and exhaust system can show corrosion if not cared for. The original seat covering was prone to ageing and damage, and bikes used heavily off-road may show wear at brake components and swingarm pivots. Proper tank ventilation helps prevent internal corrosion. The mechanical construction is generally reliable, provided regular maintenance and original parts are used. Official BMW service booklets and schedules are available to assist with upkeep.

Engine and Performance, Transmission and Handling

The air-cooled, 797cc boxer delivers smooth power and strong torque across the rev range, making it capable both on-road and in rough terrain. The five-speed gearbox, paired with BMW’s signature shaft drive, ensures smooth power delivery and low maintenance compared to chain-drive alternatives. The light chassis, high ground clearance, and 21" front wheel allow effective off-road performance. The original Metzeler Enduro 1 tyres are still regarded as a good fit for balancing road handling with dirt capability. In rally competitions such as Paris Dakar and the Six Days, the R 80 G/S proved its mettle against demanding environments.

Popular models include:

1. R 80 G/S Paris Dakar – Recognised for its larger tank and association with rally racing.
2. Standard R 80 G/S – Favoured for versatility and relative mechanical simplicity.
3. Dakar-Kit conversions – Featuring aftermarket or original accessories for extended adventure use. undefined

Interior, Comfort, Exterior and Design

The R 80 G/S’s design features a high, robust saddle (ideal for taller riders), a steel tubular frame (typically black painted), and plastic rear lights and indicators. Standard colour schemes included white with blue decals for the Paris Dakar, and more classic combinations for the standard versions. Functional details such as a single high-mounted left exhaust silencer, simple dashboard with basic instrumentation, and optional accessories like larger tanks or engine guards emphasise durability over show. Original seats had single seams, and some factory accessories included crash bars, panniers, and windscreens. Genuine model years have chrome controls and period-correct switchgear.

Other relevant features

BMW provided official maintenance manuals and service logbooks for the R 80 G/S. An F.M.I. historic registration certificate is available in Italy, making it eligible for classic motorcycle events and reduced taxes in specific regions. The model’s rally pedigree from events like the Six Days and Valli Bergamasche further enriches its heritage.

Summary

The BMW R 80 G/S, built between 1980 and 1986, is the archetype of classic dual-sport motorcycles. Notable for its 797cc boxer engine, Monolever rear suspension, practical shaft drive, and unique rally-ready Paris Dakar edition, it commands interest from riders and collectors seeking reliability, durability, and versatility. With both supply and demand entirely centred on this specific model within BMW’s classic inventory, the R 80 G/S holds a unique place among the brand’s historic motorcycles.
