Hi guys. Ive just bought my first sports bike ( ZX10r D6F 2006 ) after owning a 2009 Hornet for a while, and although I love my RST Paragon 5 jacket and trousers, i think its time to get me some leathers. I havnt been to try anything yet, as the winter is closing in ill be using my bikes a lot less till the spring. But id like to see if i can get a bargain over the winter and wondering if anyone here has the same height and build as me, and if so, wheres a good place to start for fitment or any specific suits youve tried that work. I tried my brothers BSK 1 piece on and its a 44 or something, and it hangs off around my arse, and its short on the arms. Hes an inch smaller but about 4 stone heavier. Im a lanky git at 6'3 and about 11st. I know what youre gonna say, eat more lol, or youll get fatter when your metabolism slows down......i eat good, i eat as much shit as i like, I dont go to the gym or train anymore as well, i just cant be arsed, Im 38 and just think this is what my genetic make up has decided im going to be ( can thank the old man for the hair line aswell, bast*rd ). So whats recommended ? A few mates have said to get one made, or buy off the shelf to as close a fit as possible and get it tailored, or just try everything in sight on till you find that unicorn. Now Ive seen a few suits that i do really like, im just wondering how much wizardry can a leather tailor do to make it fit without compromising its integrity ? Im thinking a 1 piece as I want to start doing some track days. Opinions, experience, guidance very welcome. Thanks guys.
