You do ask some questions!!!
When the 885 came out in 99 i ordered an aftermarket pipe straight away,when it came it didn't fit!!,the dealer ordered another that didn't either,they then ordered a 3rd and on Triumphs instructions the dealer had to fit it!!! it didn't fit.
I knew who was makeing the pipes and went to see them,all they had was jig that they the made straight through pipe on,but they had never fitted one to a bike,while i was there they phoned Triumph,the guy on the end of the phone had a dickie fit about me being there,but it soon got sorted.
The collector box was Triumphs way of getting more low down grunt,as soon as the bike was launch they realised they'd dropped a clanger and it should have been 955,the kit was their way of squeezing that extra bit out of the motor,and two years latter they dumped it,with arrival of the 955 were with extra cc and horspower covered all the angles.
How do i know all this tosh?? went to the factory on a Tiger visit and asked e'm,includeing why the first Tiger wasn't 955 they told me i was wise with hindsight!!! it was a matter of months after the launch!! yea sure!!.
