Claude (AI tool) came up with this:-
Good news for you — your WR250R should be fine. The key distinction in the regulations is clear:
The regulations will not apply to registered, on-road motorcycles that are safe and legal for road use. (Publicnow)
The law targets off-road motorcycles — i.e. unregistered, uninsured bikes with no road-legal status. Your WR250R, being taxed, insured, and registered, falls outside the scope of Grace's Law.
That said, there is an acknowledged grey area around the definition. The Department of Transport's lawyers were specifically tasked with working on a legal definition of "scrambler" (The Irish Times) as part of drafting the regulations, which suggests the line between a road-legal dual-sport and an off-road scrambler wasn't entirely clear-cut from the outset.
In practice, the distinction comes down to registration status rather than appearance. A Yamaha WR250R or similar dual-sport that is properly registered and road-legal is a different legal category to an unplated pit bike or MX bike being ridden in a park. The regulations are clearly aimed at the latter.
One practical note: dangerous driving offences and all relevant road traffic laws continue to apply (Publicnow) regardless, so how you ride it still matters.
The 'Public now' article it references says:-
The regulations will not apply to registered, on-road motorcycles that are safe and legal for road use.
