Help ZXR250 bars

have picked up a zxr250 , was after suggestions on a different set of bars , wanting to put a thumb rear brake on left side but wont be enough room so the bars need to be longer than standard, also want to raise them slightly , any ideas zxr 400 maybe?? open to any ideas.. thanks

 

These should fit, just measure the forks where the bars are to get the correct diameter but I believe they are 50mm

good point ,will check measurements but might have to buy them first
