oh wow :O that's a big margin damn!187.2 km/h is about 20 mph slower than the record for IOMTT, not that it matters, just a comparison.
You listed tracks. The IOM is a road course. The Ulster GP is also on a road course, and the lap record on the Dunrod course is faster than the IOM. The tracks usually have one, just one, section where top speeds can be reached. The road courses have many miles where top speeds can happen. The IOM probably has about 25 miles where speeds well over 125 and faster be reached. Not unlike your local freeway. There are of course corners and tight sections, but not much compared to the fast sections. There is plenty of viewing on Youtube. UKoh wow :O that's a big margin damn!
I agree 100%.I've seen that speedo reading 204 mph in the IOM videos.
Those guys are NUTS!
