The 991 Twinwall® is a new 1-1/8” braced handlebar bend that will appeal to the shorter adult rider but will still be
acceptable for a broad range of physiques. The 991 Twinwall® replicates the 672 Fatbar® which was first created
by Renthal® for the Suzuki RM/RMZ range from 2006. It was later adopted by KTM from 09-12, followed by
Yamaha in 18-.. on the YZF range and can now be found as original equipment on the very popular 2023
YZ450F.
With a relatively low height of 85mm and a sweep spec of 56mm, this positions the control area of bars closer to the
rider, reducing the size of the rider triangle. The 991 Twinwall® fills a void in the Twinwall® range smaller riders have
been asking for, in addition to helping adult riders looking to decrease the size of the rider triangle.
The 991 Twinwall® is the handlebar of choice for Monster Energy Yamaha MXGP rider Glenn Coldenhoff.
