Ducati Starter Motor 12V 13-Tooth

Superbike 749 / 999 / 1098 | Monster 1000 & S4R | Multistrada 1000 & 1100 | Sport Touring ST3 / ST4

This 12-volt, 13-tooth starter motor is a direct-fit aftermarket replacement for the Denso unit used across the air-cooled and Testastretta Ducati range, from the 749 and 999 Superbikes to the Monster S4R, Multistrada 1100 and Sport Touring ST3.

Built to meet or exceed the original Denso 428000-1070 specification, it delivers the cranking torque needed for high-compression L-twin engines - including the hot-start conditions where a tired original starter typically struggles.

Frequently Asked Questions

Will this fit my Ducati without modification?

Yes - on the models and year ranges listed above it is a direct replacement for the original Denso starter, using the same mounting flange, connections and 13-tooth pinion. No wiring or bracket changes are needed.

What are the symptoms of a failing Ducati starter motor?

The most common signs are slow or laboured cranking when the engine is hot, a single loud click with no rotation, intermittent starting that improves when the bike is cold, or a grinding noise indicating worn pinion teeth.

Is this the same as the original Ducati part 270.4.005.1A?

It is a new aftermarket equivalent built to the same specification and dimensions as the OE Denso unit. The OE number is listed for cross-reference only - the part is not manufactured by Ducati.

How do I confirm this is the right starter for my bike?

Check your existing starter for the Denso number 428000-1070 or the Ducati number 270.4.005.1A, and confirm it has 13 pinion teeth. If your bike is not listed, send us your VIN and we will confirm fitment before you order.
