We push them as far as we can dan but limited in what can be achieved with the length of the grass, also running BRP's lowers COG and makes even more drag. The field I got 70.2mph on the max I'd got with a small bore on the same field was 51 if memory serves, that's a massive increase. I've been down Arron's end and actually had a race his is a 71 mine 48, and it was embarrassing tbh. Tbh mine was only getting 14k iffy coil limiting revs, but he'd have won anyway. The vids don't do justice at all Arron's just sits on its ass and it's gone ??♂️ Although I'm waiting for him to have a rematch down my end, then I'm sure he will get some record off road speeds because the fields plenty long enough.
