I have a GT1000. I ride at fairly high speeds on rural and mountain roads. Very twisty sections. I am concerned about flat tires. I know the GT1000 has a tube, but if it blows out will it stay on the rim in the same way tubeless tires will? I think it sports a tubeless tire, but does it clinch the rim in the same way as true tubeless rims? If I want to buy a spare rim set to use on these speedy/twisty junkets, can I do that? What rim would I use? Can I port a 17 inch rim from one of the single-swing-arm bikes? Cheers, Mike
