Euro 3

Key changes

The body stays the RSV-style shape. The engine management does not.

Dell'Orto VHST 28 with a throttle-position sensor and a carburettor heater, and a combined EFI Technology ECU.

Two catalysts. RD is the 11 kW bike. RM is the open bike.

The homologated 18 kW for the RM is disputed in the brief: it may describe the exhaust.

Special editions and replicas

Per Hartrusion, as recorded in the research brief, “Replica” means the decal scheme. The mechanical bike is the standard model of that year and code.

This is the last two-stroke, and it wears the previous bike’s clothes. From the kerb it is the RSV-style machine: twin headlights, angular fairing, radial brakes. Under the tank the carburettor is no longer a plain PHBH 28. The brief gives a Dell’Orto VHST 28 with a throttle-position sensor and a heater, a combined ECU from EFI Technology, and two catalysts. The codes are RD for the 11 kW bike and RM for the open one. The years in the brief overlap the PY, because some sources date by build and some by registration: 2007/08 through 2012.

Power, carefully

RM is listed at 18 kW homologated. The same sentence in the brief records a dispute: the figure may belong to the exhaust rather than a measured engine output. Quote it as a homologation note, not as a dyno result. RD is 11 kW. That is the restricted code, and it is the figure that lines up with the current A1 class. Whether a particular imported RM has been restricted in the UK, and with which parts, is To verify on that bike.

The TPS ignition is the piece Hartrusion is recorded as rating well, against a general reputation for fussiness. Both can be true. More sensors means more things that can unplug, and a better spark map does not cancel a blocked catalyst.

What you are diagnosing

The brief lists the TPS, the carburettor heater, an air-temperature sensor and extra-air hardware, on top of the twin catalysts. A starting or mid-range fault on one of these is not automatically “the CDI bridge” from a 2004 Nippondenso. The ignition is the ECU. Pinouts, sensor voltages and the test procedure are To verify in the manual. This site will not invent them.

The 2006–2010 parts catalogue PDF covers part of this run and the PY before it. It is a reference, not a set of numbers copied into the parts directory. Read it for the VIN you have. Year letters A, B and C are in the brief’s table for 2010, 2011 and 2012. Codes for 2008 and 2009 are not, and the decoder marks the ISO reading To verify.

Liveries

Rosso Fluo is 2008 in the generation record. Spain’s No.1 and Talmacsi sit in the 2007–2009 group, years To verify. Max Biaggi SBK / Alitalia is 2010 and is verified from Decalmoto and 2strokebuzz. Full Black and Full White are named without exact years. The four-stroke RS4, which overlaps the end of this run from 2011, is a different motorcycle. Do not order a VHST needle for one.
