MX ATVs are light and durable, which encourages high-speed action.
Newman expects the quickest racers this weekend to go faster than two-wheel riders do around his track.
As of yesterday, over 35 riders had registered to race across the variety of classes.
Newman said numbers were likely to be down because of it being so close to Christmas and the Covid-19 pandemic, but with registration open up to race day, more entries were expected.
The champs are being held at Waiomoko Road at Whangara.
Entry is free to the public and racing starts at 10am tomorrow and Sunday.
