So Whats New?


Traditional Rocker



Answer No 1 - Roller Rockers


You may ask why hasn't anybody just increased the capacity of 
a pitbike engine more than 160cc ? The answer is technical but with the help of
our WPB Race engineers we 
will try to explain.
 
The Extra 10-15cc over a standard stock engine requires a major
engine head rethink, the valve springs have to be uprated a considerable
amount, this puts extra pressure on the cam and increases the drag on the engine
the effect is a diminishing return of power for the extra CC's added.
The Detroit 170 Cam followers have rollers fitted instead of metal pads, this greatly reduces friction and frees up huge chunks of Power.
Also the Detroit has an Aggressive cam profile, rapid valve opening requires steep cam profiles and that profile has to be followed exactly,without error.
The Roller Rockers of the Detroit together with the heavy weight valve springs
means that we are exclusively able to provide Pitbikes to customers with a factory
fitted 170 engine.

When you consider the aftermarket retrofit of converting
a 150cc or 160cc to a 170cc the costs are huge.
New Barrel, New Head, Gaskets Time and Labour 
£££'s

Detroit 170 Customers will now be able to ride the biggest Engined Pitbikes 
in stock form.
No more expensive Retro Fit Head Conversions are Required.

 The Detroit 170 cc is Here and its putting that power down in the dirt,  
exactly where you want it, MORE POWER to get you those Race Wins.
