Hey FLUX... how old are you?Ok, maybe I'm being unrealistic. I'd like to reach around 340lbs lubed but no fuel (ie. half-wet).
421lbs wet means 30lbs of fuel, so a Street Triple is starting out at 391lbs half-wet.
-22lbs for the exhaust option => 369lbs
-2lbs for replacing steel licence holder with aluminium => 367lbs
-4lbs for 520 alloy sprocket/chain option => 363lbs
-3lbs for removing pillion pegs => 360lbs
-2lbs for fitting unweighted flat & wide clipons => 358lbs
-1lb for using bar end mirrors => 357lbs
-1lb for light-weight headlight change => 356lbs
-1lb using Daytona 675 2009 magnesium engine cover => 355lbs
-2lbs using titanium bolt kit => 353lbs
-??lbs using 10 spoke forged magnesium rims => 34?lbs
Anything more that could be gutted/removed, while keeping it street legal? Obviously the goal here is featherweight.
Wanted to participate in this thread, so I started converting the feudal measures you were using into something more comprehensible then I noticed noticed you were from Melbourne.:signhuh: Australia metricated in the late '60's dude..... I'm 47 years old and I was never taught Imperial Measures in school in Sydney.:biggrinjester:
On issue to think of is the KTM690SM has a considerably lighter engine than the 675 Triumph Triple engine so matching the 690 weight is unrealistic.
However I have ridden another brand of 600cc bike before and after fitting lightweight wheels and the difference was huge... from what you have written you are looking for weight reduction to change flickability on twisty roads. If that is the case don't bother with anything other than removing pillion pegs and stuff, then go for the super lightweight wheels. AMCN had a good article on putting lightweight wheels on a cbr600rr a year or so ago ( lots of suspension fiddling needed to get them to work, but with good results) so give them a call.
BTW only three countries have not adopted metric measures. Liberia, Myanmar (aka Burma) & USA... what a club :rofl2:
