What the update means
A shorter wheelbase and lower unsprung weight make a bike turn more quickly and follow bumps better, which is the point of the update. The bar move makes the riding position more upright and relaxed. The wet weight matches the 1200 Speed Twin's 476 lb.
The Speed Twin 1200 costs $15,395.
Price and weight beside its siblings
The Scrambler 900 is listed at $12,395 and 492 lb. So the Speed Twin 900 is 16 lb lighter than the scrambler with a 0.3 in lower seat. The Bonneville range around it includes the Speedmaster at $13,995 and the Bobber at $13,995.
Kawasaki's Z650RS is $8,999 and 412.3 lb curb, and is the lighter, cheaper rival.
