yeah they should fit. plenty of room for them
your speedo could be out depends on what size tyres u get

the profile of the tyre... if theres 2cm of rubber or say 4 it will create a different ratio and the speedo will be out... 19" are a big step up afaik and as long as u get low profile rubber it should be right?? correct me if im wrong but logically to me thats right

19's will fit BA's easy, it throws out your speedo but afaik you can get them recalibrated.

I had 18's on my old pulsar (cough cough rice i know
 )
I got caught by a copper, he got me for 74 and my speedo was saying 62/63. Sold it b4 I found out if the wheels were the cause of the off reading tho.

again it matters on the profile of tyres... exp; 15' wheel with 4' of rubber; 19' stock you will have to match this with your new wheels so the bigger the rim the smaller the rubber, so that you can keep the ratio the same. note; measurements thought of top of head 
hope that helps...

nah you shouldnt have to, if you get 18's i will bring you closer to your actually speed but should push you over the limit. ie - on 15's when your speedo says 100 you will actually be doing approx 94 but with 18's at the the same speed you will me doin say 96. ive got 18's on mine and it may have jumped up a k or so. you would only need to adjust your speedo if you increase the rolling diameter of the tyre. having said that adr rules state that rolling diamter of a wheel must not be increased by more that 15ml of the originial specification

mm ba spedo is done by the abs sensors in the rear wheals... so a rim/tyre change wont be a problem for the spedo!

Is that done from the outside of the tyre? If not and its measured from near the centre it would still affect the speedo. Wouldnt it?

A guy on one of the XR6 Turbo cruises has 19's on both his XR6T's, he said it affects the speedo. |
