How soon is soon?

I feel a little Art of Noise is appropriate...

How rapid is rapid?
How quick is quick?
Hurrah!

First run of LC4-50 motor

Today was a milestone in the development of our project Dakar LC4-50 motor.After many months of work by all parties, encouragement in our idea, and some doubting, we finally achieved the goal of hearing the special short-stroke 450cc LC4 engine run for the first time at Torque Racing HQ.

Martin Wittering worked tirelessly to get the engine built so that we could fit it into a donor KTM690 Enduro and take it with us for testing in Spain next week.

The bike started on the button, and ( no surprise) sounds like a 690, although a little softer off the bottom-end, and this was without the chance to do any re-mapping of the EFI system with our software.

It is an excellent pick-me-up for all those involved in the translation of our initial idea to make a "clubman" Dakar bike for those riders with redundant 690RR or 690 Enduro bikes, using a short-stroke crank and Cosworth high compression piston.

The 5 riders from UK & Malta who were going to Transanatolia Rallye in Turkey with Torque Racing are now going on a 1000km roadbook trip in Spanish Pyrennes, due to the late cancellation of the Transanatolia by the organisers.
Well done to Donna & Martin for arranging this trip at the last-minute so that we all still get to ride our rally bikes.
It will also be a good test for the new engine, plenty of miles, but without the strain of racing.

Hi KtmMitch
I have an '08 690 and am interested in this hi compression piston of yours. The '08 (654cc)has a 102 mm bore, i'm not sure if the newer 690's(690cc) have the same bore? What size is this piston of yours? Will I have to bore my barrel and re-plate?

All 690 & 654cc motors have same bore & cyl head detail.Our hi-comp Cosworth pistons will work with either engine, no boring or re-plating required.

Mitch, I know your main focus is rally racing but your products show up on a lot of 690s built up for adventure riding. Have you ever considered putting together a wide ratio gear set for the 690 to make it more useful for that purpose?
