BMW R45 Classic Review: Retro Boxer Charm with Timeless Styling & Everyday Rideability

by

The BMW R45 was first introduced in 1978 as part of BMW’s air-cooled boxer lineup, offering a smaller displacement version of the R-series motorcycles. Its classic teardrop tank, round headlamp, twin-pod analog dials, and minimalist rear end give it that pure retro appeal. With exposed engine fins and a low-slung stance, the R45 exudes timeless old-school charm that still turns heads today among vintage bike collectors.

Air-Cooled Boxer Twin Engine

At the heart of the R45 lies a 473cc air-cooled flat-twin “boxer” engine, producing around 35 hp at 7,250 rpm and 37 Nm of torque at 5,500 rpm. It delivers a smooth, balanced ride with its shaft drive system and low vibration levels, thanks to the engine’s inherent mechanical harmony. The unique side-to-side engine layout adds to its character, especially when revving or starting up.

Lightweight and Rider-Friendly

Weighing around 195 kg (wet), the R45 was built as a smaller, lighter alternative to BMW’s larger touring bikes like the R90 or R100. Its manageable size, low seat height, and narrow frame made it a favorite for beginner and mid-level riders. It’s also agile enough for city cruising and steady enough for weekend highway stretches.

Mechanical Simplicity & Reliability

The BMW R45 is known for its mechanical simplicity, featuring a 5-speed gearbox, shaft drive, and twin-shock rear suspension. It’s a dream for DIY mechanics and vintage restorers. While it lacks modern electronics, its bulletproof build and low maintenance needs have earned it a cult following across Europe and beyond.

Collector’s Status in India

While never officially launched in India, a few units of the R45 have made their way here via private imports. Today, it’s considered a collector’s gem, especially for vintage BMW enthusiasts. Restored models can cost anywhere between ₹3–6 lakh, depending on condition and originality.

Conclusion: The BMW R45 may be a small-displacement bike by today’s standards, but its retro design, air-cooled boxer engine, and riding charm make it a true classic. Whether for restoration or weekend vintage cruises, the R45 still delivers a unique blend of simplicity and soul that’s hard to match.
