Ducati Monster S4R (2004-2006) Maintenance Schedule

This is the maintenance schedule and service intervals for the Ducati Monster S4R, released in 2004 to replace the Ducati Monster S4.

Like the S4, the Ducati Monster S4R is powered by a superbike motor — but from the superbike next in line after the 916, the Ducati 996.

Here are all our Ducati Monster maintenance schedules:

The motor in the Ducati Monster S4R is re-tuned slightly for more midrange torque, but the S4R remains a powerful weapon. It’s a 996cc liquid-cooled fuel-injected 90-degree L-twin with a compression ratio of 11.6:1. It makes max power of 83 kW (113 hp) at 9500 rpm, and 101 Nm (74 ft-lb) at 7000 rpm.

Like the Monster S4, the S4R has a dry clutch and a chain drive.

After two years, Ducati went to the next level and replaced the S4R with the even more powerful Ducati Monster S4Rs, borrowing the engine from the 999.

About the Ducati Monster S4R

The Ducati Monster S4R was a fast-follow update to the popular Ducati Monster S4.

Like the original S4, the Ducati Monster S4R is a standard/sport bike with a superbike engine in it. But this time, it was the engine from the Ducati 996 superbike (which followed the 916, whose engine was in the S4).

The heart of the S4R is a 996cc liquid-cooled fuel-injected 90-degree L-twin (a V-twin with a forward tilt) with a compression ratio of 11.6:1.

The engine in the S4R makes a max power of 83 kW (113 hp) at 9500 rpm, and 101 Nm (74 ft-lb) at 7000 rpm. These specs are actually similar to those of the 996, just at different points in the rev range — the engine isn’t so much “de-tuned” as “re-tuned”. It still has a 10500 rpm limiter and charges all the way up — it’s a very different feeling from air-cooled engines that preceded it.

Like its predecessor, it’s a DOHC 4-valve-per-cylinder design, with belt-driven valves. So owners need to bear in mind that when those valve service intervals come up every 10000 km (or 6000 mi), there are twice as many clearances to check. And one must usually keep spare belts on hand in case they need changing. The final drive is via a hydraulic dry clutch (easy to fix, thankfully!) and chain.

So if you want a liquid-cooled high-power monster with the characteristic Ducati rattle of a dry clutch, the S4R is one of your last options — if you can still find one.

It’s amazing how much there is to say about the S4R without talking about its aesthetics. Whereas the original S4 got its handsome but dated looks from the Monster 1000, the Ducati Monster S4R got a serious upgrade.

The Monster S4R has a single-sided swing-arm and swept up exhausts that reveal that beautiful rear wheel. It comes with a seat cowl and small deflector which give it a more sporting edge. It’s just a much nicer bike to look at, which is a great bonus since it’s also more powerful.

Front suspension on the S4R is a 43mm Showa inverted fork with full adjustability (preload, rebound,and compression damping), and a fully adjustable showa rear shock.

Braking is also high-grade, with huge 320mm discs up front and Brembo P4.34B four-piston calipers on the front disc. Rear brakes are Brembos too (P32F).

Ducati replaced the S4R in 2006 with the Ducati Monster S4RS, which got the engine from the Ducati 998 superbike. The S4R Testastretta was similarly spec to the S4Rs.
