2018 R NineT Urban G/S - Pros & Cons

Strengths

Strong power output: With 81 kW @ 7550 rpm and 116 Nm @ 6000 rpm of torque on tap, the R NineT Urban G/S is no slouch for its class.
Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
Low-maintenance final drive: Running Shaft final drive cuts out the regular chain cleaning and tensioning that most bikes need.

Considerations

Tall seat height: At 850 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.

Wear Points & Servicing Notes

Heat management in traffic

Because the R NineT Urban G/S relies on airflow rather than a coolant jacket, expect noticeably more radiant heat at low speed and in traffic. It's inherent to air cooling, and ventilated gear largely offsets it.

Fuelling & injector care

The Electronic intake pipe injection / digital engine management with overrun cutoff on the R NineT Urban G/S needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

Brake disc and pad wear

Braking up front comes from 2 x 320 mm Foating brake discs, 4 piston radial calipers - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The R NineT Urban G/S's suspension runs Telescopic forks, 43 mm fixed-tube diameter at the front. The rear uses Cast aluminium single swinging arm with BMW Motorrad Paralever; central spring strut,spring preload fully adjustable by hook wrench, adjustable rebound-stage damping. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The R NineT Urban G/S uses shaft final drive: essentially maintenance-free day to day, with periodic gear-oil changes the only real service item.

Frame & chassis check

Built around a Three-part frame concept with front frame and two-part rear frame, load-bearing enginegearbox unit, rear-set frame removeable for one-up riding, the R NineT Urban G/S's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

Handling the weight at a standstill

221 kg puts the R NineT Urban G/S toward the heavier end of its class. It's most noticeable at walking pace; once underway the mass settles into the handling rather than fighting it.

R NineT Urban G/S - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2018 BMW R NineT Urban G/S, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy R NineT Urban G/S should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a R NineT Urban G/S's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Fuel system care

Fuel injection on the R NineT Urban G/S needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
