2009 1125CR - Pros & Cons
Strengths
-
⚡
Strong power output: 2009 Buell 1125CR makes 109 kW @ 9800 rpm with 111 Nm of torque - competitive figures for its class.
-
⛽
Large fuel range: The 21.2 L tank is generously sized, translating to extended range between stops - ideal for touring or longer commutes.
-
⚙️
Low-maintenance final drive: Belt final drive means no chain to clean, lube or adjust - meaningfully less routine maintenance than a chain-driven equivalent.
Considerations
-
ℹ️
Age-related wear: As with any used 1125CR, a thorough pre-purchase inspection covering consumables, service history and tyres is always recommended.
Wear Points & Servicing Notes
Cooling system servicing
The Liquid cooled system on the 1125CR needs a coolant change roughly every two years (or per the service schedule) - skipping it lets the coolant turn acidic and corrode the aluminium water passages over time.
Suspension condition on used examples
Up front, the 1125CR runs ø47 mm Showa inverted forks, adjustable compression damping. rebound damping and spring preload. 120mm wheel travel and 120 mm at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.
Final drive maintenance
Final drive is by belt - lower maintenance than chain with no lubrication needed, but tension and tooth wear should still be checked at service intervals.
Frame & chassis check
The frame is Aluminium frame with fuel in frame. - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.
1125CR - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2009 Buell 1125CR, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained 1125CR should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task on any 1125CR. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.
Fuel system care
The 1125CR's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.
