Ah...so there was interest and someone trying to have them made.
When I saw Bubba's Racing ....I thought of BHP Racing (Bubba's House of Power Racing - they're in Arkansas) so not the same.
With Seat pans being Vacuum formed.....it shouldn't be too hard to get a mold made and have them produced.....I know the 86-87 would be easier as the 88-89 has the front seat mount integrated into the pan.
Hopefully they will be available....it'll really help keep the 250R alive!
