Sorry for delay , had to sleep . First off , Jake , the wheels are not the R BST , actually can't remember if they were available at the time I pulled the trigger , I bought my first set a bit staggered in time . But feature everything mentioned extra on the L2 fitted set , and also the spare set .
Now , one of our clan BigDev , had an unfortunate incident with his front BST , on his hyper supercharged beast , and wasn't even giving it a spanking at the time , but I believe the bike was cranked over , or at least turning / leaning in to a degree . The damage was substantial enough to have to replace it at his own expense , albeit at cost from BST . It was actually a pothole if I recall correctly . Now , I can't say I'd like to hit too many potholes straight on , let alone bang on an apex , or even at speed limit in urban jungle . Honestly , I scan road surface generally , as best as one can expect , so there is always a potential surprise ' on any Sunday ' ride . So there is still that risk , but to be honest , I have had the same concerns with magnesium rims over the years , and have been lucky . If you live and ride in an area that has neglected the road upkeep , to some alarming degree ( very possible nowadays ) , well you may want to rethink things a bit more .
Now , i run my BST front with 38 psi and the rear 38-40 psi , and my cut off ride temp is 35 degrees Celsius , as an ideal . Now I run this pressure because of my fat ass , and don't worry , they are still compliant Bridgestone RS10 , and sure footed , with some cushioning give .
If , like you Jake , you are building / built a full house motor / chassis / street weapon , not so much a swervery king or 1/4 mile killer , but still well able to effectively negotiate any streets to your favorite road locations , well even then , the BST's would be a top addition to your creation bro .
Sure , it's a ton of money no matter how you look at it , and tranfer that $ to motor enhancement , that's a lot of potential extra poke that could be had .. guess you have to make your choice , based on one's wants
and needs .
