A New Breed of Superkart - T.A.G. 450cc 4Stroke V-twin

An innovative and enterprising company, NLR system s, is developing a new superkart package which poromises to revolutionize the sport.

The Superkart which features an Anderson Chassis, uses an Aprilia V-twin 450 four stroke motor with on-board electric start and - get this - will feature an intercooled turbo charger.

The stock Aprilia 450F makes only 50HP hence the need for a turbo to bring power inline with the 250cc 2stroke F/E Twins which typically make around 90BHP.

The on-board start is meant to eliminate the need to push start these $30k just to get started.

For details of the project see:

If this succeeds I might consider getting into Superkarting myself...

Yamaha's WR250FK 4 Stroke Shifter Kart

For the longest while I have been increasingly convince that Karting is sorely lackking the backing of a major auto manufacturer. For many years the only major manufacturer to have a purpose built engine has been Yamaha with the KT100 series 100cc 2 strokes.

Now it turns out that in addition to that venerable machine Yamaha has added not only a pair of 2 stroke shifters:

i) A 12cc 2stroke - the YZ125K

ii) A 85cc 2stroke - the YZ85K

But also a 250 4stroke shifter - WR250FK

This Kart is being promoted in Mexico as part of its 250F Superkart Series

But for some strange reason the engine is not listed on any English speaking Yamaha Web site or apparently being made available in Canada or the US. I only hope more people will find this package about this and this situation will soon change. For this could be the first step in moving (shifter) karting into the modern 4 stroke era.
