The list is taken from the official Piaggio spare parts catalog (B2B area), Gilera Nexus 500, Piaggio X8 125/200, X9 125/250/500 sections, and Historical Catalogs 1998-2005 Piaggio and Gilera. If your scooter is not in the table, send us the VIN and we will verify the correct code before you order.

Who is it perfect for

This is the spare part for those who feel their X8, X9 or Nexus steering "clicking" in the center, wobbling in a straight line, or stiffening during maneuvers: these are classic symptoms of races worn by rollers after years of potholes and braking. It's also the right purchase for anyone putting a long-idle X9 or Nexus back on the road, or for a workshop that wants the complete original kit — bearings, nuts, and dust cover in one package — instead of chasing individual components. With the new set and adjusted preload, the maxi-scooter will corner with the precision it had when new.

Frequently asked questions

Which scooters does the Piaggio 5982615 race group fit?
Code 5982615 is provided by the Piaggio catalog for X8 125 (also Potenziato) and X8 200, for the entire X9 range — 125, 125 SL, 180 Amalfi, 200, 250 and 500, including Evolution, Potenziato and ABS versions — and for the Gilera Nexus 500, including SP, up to 2011. Exact versions, markets and years are in the table above.

What exactly does the kit include?
The complete steering head assembly: the two tapered roller bearings with their respective races, the threaded adjusting nuts, the spacer, the washers with the lock washer, and the dust cover. This is everything that works inside the steering head: no other spare parts are needed to complete the replacement.

Where exactly is it located on the vehicle?
In the steering head, between the frame and the fork stem: the lower bearing works above the fork plate, the upper one below the adjusting nuts. In the catalog, the kit is in the "Fork" table, position 1, and on the X9 500 in the "Fork-Race Group" table, position 17.

How do I know if the races need replacing?
Typical symptoms are a click or notch in the center when turning the handlebars, vibrations or wobbling in a straight line, steering that stiffens at low speed, and a "thunk" from the front end when braking. If you feel play when lifting the front wheel and pulling the fork, the assembly needs to be replaced.

Is it an original Piaggio spare part or an equivalent?
It is the original Piaggio spare part with code 5982615, new and never fitted, the same kit provided by the manufacturer for these frames. Bearing measurements, nut threads, and dust cover are those of the original equipment. It is shipped from Italy with invoice and manufacturer's warranty.

Can I install it myself?
Workshop equipment is needed: the handlebars and fork are disassembled, the old races are extracted from their seats, and the nuts are tightened with the dedicated wrench, adjusting the preload. Incorrect preload will make the steering stiff or leave play: if you don't have the tools, entrust the installation to a mechanic.
