i need to buy a jacket alpinestars either dyno, stunt, or tz-1
any suggestions on the best and what size should i be the chart says 52 but some say bigger if i am 6 3 and 195 lbs. b/c most sites dont have my size so i think that i am wrong

it has us -> euro conversions

Be careful on the Euro Sizing...I have the V4 two piece and had to get a Euro size 56....I am 5'9" 195lbs......If I were you I would go for a two piece suit....I know www.motorcycle-superstore.com is selling the V4 2 piece for $532...and most Alpinestar jackets cost about $300......For $200 bucks you can protect your legs too...

Best bet is to try it on somewhere.....or get it online with a company that has a good return policy, order the two sizes you thinking about and return the one that does not fit...

i tried a couple on this weekend
