Erin Sills did 381km/h on a S1000RR in Bolivia.Her world record for naturally aspirated bikes got set at 369km/h though as she was able to do this speed both ways !
Faster than any supercharged Kawasaki...let alone with Arseys fat azz on it...
As for weight comparisons I put my GS ADV on a scale with aluminum bags and full tank and it came in at 268 Kg.My friends 1290 SuperADV with plastic bags and full tank weigh in at 256 Kilos...12 kilos difference and my GS-ADV still steers quicker than the KTM and does not wobble at 135...
As also I much rather have T-L that does not dive and is way more comfortable on bumpy roads and a clean drive-shaft...
