Owner report 11749237 · 2026-07-09 (July 9, 2026)
I was making a right turn at an intersection while in 3rd gear with the clutch engaged, and the motorcycle stalled. I was able to restart the motorcycle while executing the turn and completed the turn without incident. Failure to do so would have put myself at risk from oncoming vehicles through the intersection. When this has happened the low oil pressure indicator illuminates. The oil sight glass shows oil level to be at max. I use ExxonMobil 93 fuel. I had taken the motorcycle in to conduct service for the same issue (the motorcycle stalled…

Owner report 11660245 · 2025-05-11 (May 11, 2025)
I had been riding on a road for about 15 minutes at speeds ranging from 40-50 mph. As I came to a stop sign, I downshifted and used engine braking to assist the brakes in slowing down. After I downshifted from 3rd to 2nd gear, the engine quit and all dash lights illuminated. I pulled the clutch, pressed the starter button as I coasted, and the engine re-started. The engine ran fine before and after the incident. This happened at approximately 1,600 miles. This is the second time this happens under similar conditions: downshifting from 3r…

Owner report 11653225 · 2025-04-07 (April 7, 2025)
The motorcycle cuts out when slowing down, engine just dies, but all the electrical stays on. This is a brand-new bike with only 500 miles on it. It happened while I was riding, and I suddenly had no power. Luckily, I was on the right side of the road and managed to coast to the shoulder safely, but it could’ve gone a lot worse. There were no prior warning lights. I scheduled an inspection, but the earliest appointment isn’t until later this month. In the meantime, I did some digging, this doesn’t seem like an isolated issue. A quick search show…
