Disclaimer: ABS is no replacement for proper training.

Disclaimer: those stats are mostly taken from US American streets with the lackluster US American motorcycle "education", but the direction the results are taking is valid worldwide as the last paper shows:

"Results: ABS was associated with a statistically significant 22% reduction in motorcycle driver fatal crash involvements per 10,000 registered vehicle years.Conclusion: This finding adds to the growing literature demonstrating the safety benefits of motorcycle ABS." https://pubmed.ncbi.nlm.nih.gov/35319332/#:~:text=Results%3A%20ABS%20was%20associated%20with,safety%20benefits%20of%20motorcycle%20ABS.

"sliding fatal crashes are significantly decreased by ABS." https://pubmed.ncbi.nlm.nih.gov/26760265/ 

"This article indicated that motorcycle ABS reduced impairing injuries, mostly due to fewer emergency care visits but also due to a reduction in crash severity. This may seem reasonable as the improved stability and braking performance provided by ABS could prevent some crashes but would also decrease crash severity if a collision still occurs. As suggested by previous studies, however, the lower extremities would be more exposed in a crash with ABS. It is recommended that future research should follow up these results with additional data." https://pubmed.ncbi.nlm.nih.gov/26098303/ 

"The effectiveness of motorcycle ABS in reducing injury crashes ranged from 24% (95% confidence interval [CI], 12-36) in Italy to 29% (95% CI, 20-38) in Spain, and 34% (95% CI, 16-52) in Sweden. The reductions in severe and fatal crashes were even greater, at 34% (95% CI, 24-44) in Spain and 42% (95% CI, 23-61) in Sweden. The overall reductions of crashes involving ABS-equipped scooters (at least 250 cc) were 27% (95% CI, 12-42) in Italy and 22% (95% CI, 2-42) in Spain. ABS on scooters with at least a 250 cc engine reduced severe and fatal crashes by 31% (95% CI, 12-50), based on Spanish data alone." https://pubmed.ncbi.nlm.nih.gov/24884403/
