Alternative Speedtriple Forks.

G,day peeps andy here.I have a question....I have a truimph speed triple 1050cc,I have owned it for 15 years, it's a 2007 model.My question is,my front forks are worn in the bushings,and I have been trying to source new outer tubed.These are unavailable according to truimph...I don't want to buy second hand as these could also be snagged.Is there a substitute set of folks I can use from a different model of truimph,or of any Japanese origin I can use and still buy new parts for......cheers in advance Andy.
