The North West 200 has agreed a new three-year title sponsorship deal with fonaCAB and Nicholl Oils, which will run from 2020 until 2022.
The two Northern Ireland companies were the principal sponsors of this year's races that saw the North Coast spectacular celebrate its 90th Anniversary.
"It's great news that fonaCAB and Nicholl Oils will return as title sponsors for the next three North West 200s," event director Mervyn Whyte MBE said.
"Their support is an indication of the platform the event can offer companies to promote their businesses and will help provide Coleraine and District Motor Club with the financial security required to plan for the future of the races."
William McCausland of fonaCAB said: "Northern Ireland's largest company is delighted to be returning as a main title sponsor for the North West 200 after the hugely successful 90th Anniversary event earlier this year.
"We have a long-standing relationship with the NW200 and our sponsorship of local riders has been consistent from the 1980s through to current competitors Lee Johnston, Glenn Irwin, Jeremy McWilliams and Paul Jordan.
"I myself have a long history with the North West and have many happy family memories of attending the meeting since childhood."
This news comes hot on the heels of Honda Racing's announcement that Irwin and Davey Todd, both winners back in May, will make their first road racing appearance of 2020 on the all-new CBR1000RR-R Fireblade SP around the famous 8.9mile Triangle Circuit in May.
Irwin, the 29-year old from Carrickfergus, made his debut at the North West in 2015 and has won the last four Superbike races in the region.
Hugh Nicholl, managing director of Nicholl Oils, was also delighted to confirm his company's continued support.
"This sponsorship provides us with a unique opportunity to continue our support of the team at the NW200, who work tirelessly to put together a fantastic week of racing and events for all the competitors and spectators from home and abroad, an event that my family have enjoyed attending for 20 years," he said.
Elsewhere, Skerries rider Michael Sweeney tops the chart for the first time after 25 completed rounds of the 2019 Duke Road Race Rankings Championship.
The Irish road race Supertwin and Supersport champion, and runner-up in Superbikes, had an outstanding season and follows in the wheel-tracks of last year's Duke winner Derek McGee.
Best newcomer in the series was Vinny Brennan from Swords, the Irish Junior Support road race champion and runner-up in the Supertwin championship.
• It was with sadness that the racing world learned of the death of Percy Tait, aged 90.
Tait was well known as a competitor at the North West, UGP and TT in the 1960s and 1970s and won the first 1000cc race at the Ulster Grand Prix in 1975, riding a TZ 700cc Yamaha.
