PIST-OM-DUR-87.50XS (shown left)
We have produced this Duratec piston for use with new Duratec engines as this allows you to use the original rings supplied. This means you can simply slip out each piston in turn & fit the rings to the new piston, so therefore full running-in will not be required, just gentle bedding in. Available 87.50mm Bore. Set of 4. Also available singly.

PIST-OM-DUR-87.50RXS
We also supply the RX version which comes complete with rings for those people who are using a secondhand engine. The pistons will come with the rings unfitted as the rings must be gapped when fitting. Available 87.50mm Bore Set of 4. Also available singly.

PIST-OM-DUR-88.00XS
The 88.00 version is designed for those who have a secondhand engine that shows some bore wear. We would normally recommend the engine is replaced if any substantial bore wear has occured due to the thickness of the cast in liners & would only recommend the use of an overbored engine for either road use or engines of a mild state of tune. The pistons will come with the rings unfitted as the rings must be gapped when fitting. Set of 4. Also available singly.

ROD-FD-2.0LDUR-146S
Duratec 2.0L steel rod set. We have designed this rod to replace the standard fragile item, it has a bronze small end bush, which replaces the press-fit version. Ideal for use with our piston. These rods have been tested extensively by ourselves to over 9000rpm on standard crankshaft & over 9500rpm on a steel crankshaft. So beware of cheap imitations!
Weight approx 455g
Centre to centre length approx 146mm

ROD-FD-2.0DUR-152

The new 152 rod has been designed specifically to go with our new 2-litre Duratec slipper piston, it is 6mm longer which has helped to reduce the rod angle which in turn helps to increase the torque. On our high spec engine we saw an increase of 6lbft torque & just reaching 200lbft torque. Due to the smaller pin size on the piston, this has reduced the weight of the small end of the rod which means the rod is actually 12g lighter than our normal Duratec rods. We have also upped the rod bolts to the ARP625+ high spec material to cope with the extra performance.

PIST-OM-DUR-87-50SLS

We have designed a 2 ring slipper piston for the 2-litre Duratec with the help of Omega & the latest improvements in design that they have gained through GP bike development, we have produced a new forging specifically for this piston. It is of a much stiffer construction, uses a smaller lighter pin at 18mm, we have also moved the pin closer to the crown of the piston which helps to reduce piston rock which also helps to reduce friction. It is ultra-lightweight & low friction; in initial tests we saw a 7bhp increase in our high spec engine simply by changing the pistons along with new matching rods.

PIST-OM-DUR-87-50SLBS

We have also developed a billet version of the new slipper piston design for the Duratec, that incorporates all the latest technology available into a billet piston. These detailed improvements, which are normally too expensive to incorporate into the forged piston become easier to produce in a billet version. This piston is machined from solid on a special machine that Omega use to manufacture all their GP motorbike & high end pistons. The major improvement is the bridge on either side of the gudgeon pin, this allows the piston to be made even stiffer & although this appears to be a very small change does allow the piston strength & longevity.
