One of one ZX9r . We only make one of each design . The frame is high quality seamless steel alloy , tig welded tube . The over all length is 25mm shorter than standard , with the swing arm bolt in line with the sprocket centre . This gives slightly better handling than the original machine . The engine has done a shade under 34000 , so still has plenty of go in it . Carbon wrap over a stainless collector box . The exhaust works well and is not overtly loud . Mot till next August . This bike runs rides really well and is priced to sell .
