With 2024 marking 25 years since the initial record of 156mph was set by Gary Rothwell, County Durham’s Jonny Davies aims to increase that to 160mph or more this August. The two-time Guinness World Record holder will be using a modified Kawasaki Ninja H2 SX, which features a secondary throttle fitted to the rear of the bike to allow him to continue to accelerate while skiing behind.

Having held several practice runs already, Jonny will have a few more practices before attempting to break the record on Sunday, August 18th, at Elvington Airfield. The record attempt will be part of the lineup for the 2024 Ultimate Supercar event, which will see dozens of elite sports and supercars showcase their own top speeds.

“It has been exciting watching Jonny’s progress with the Ninja H2 SX so far and to now have the record attempt date and location confirmed is fantastic. We are pleased that it’s taking place at such a well-attended event and look forward to our Supercharged machine being showcased in front of thousands of motorsport enthusiasts!” 

“I’m really excited to confirm the date and set my sights on securing a new Guinness World Record. I’ve already done several runs on the Ninja H2 SX, and while these have primarily been to start testing the throttle and other components, we have already been able to reach 120mph! I have a couple more practices before the 18th, where I will be looking to build on that speed and ensure everything is in place for the big day!”
