The 25-year-old from Bradford has signed an exciting two-year deal with the Northern Ireland outfit, which will be Yamaha’s official UK Road Racing team this season.
Harrison is one of the brightest talents in road racing and demonstrated his potential in 2014, claiming his first ever victory at the Isle of Man TT and finishing as the runner-up in the Superstock race behind Michael Dunlop.
Harrison will be on hand to meet fans and sign autographs at the Festival over the course of the weekend, when he’ll be joined by Honda Racing’s Conor Cummins.
Manx star Cummins put his 2010 horror crash at the TT firmly behind him in 2014 as he made an emotional return to the rostrum for Honda, taking third place in the Superbike race before ending the week with a magnificent performance in the Senior TT, sealing a brilliant runner-up finish on the CBR1000RR Fireblade.
The Ramsey Rocket will attend the Festival on Saturday, February 7.
World Supersport contender Jack Kennedy has also confirmed his attendance on the Friday and Saturday in Belfast.
All the very latest models from the major manufacturers will be on display at the 2015 Adelaide/Blackhorse Motorcycle Festival.

One particular machine on the GS Motorcycles stand is sure to attract plenty of attention, with Suzuki’s GSX-R1000 MotoGP ‘special’ taking centre stage, produced to mark the manufacturer’s return to the premier Grand Prix class in 2015.
The PSNI will again be in attendance to promote the BikeSafe initiative.
The motocross village also returns and visitors will be able to obtain all the information they need about events planned in 2015.
The official charity for the 2015 Adelaide/Blackhorse Motorcycle Festival will be Eilish Degnan Cancer Foundation.
The Festival opens on Friday, February 6 from 2pm-10pm and on Saturday and Sunday, February 7-8, from 10am-5pm.
