Vespa bgm PRO SC shock absorber in racing use
bgm PRO SC shock absorbers now also tested in the English BSSO racing series
Videos say more than a thousand words! Therefore, here is a brief introduction to Tony o'brien and his Charlie Edmonds tuned FALC bullet!
Last weekend Tony got the rear one bgm PRO SC shock absorber tested. The penultimate race of the English BSSO racing series took place on Mallory Park. On the racetrack, speeds are over 150 km / h without problems reached.
Here is the feedback to bgm and us regarding the damper. Unfortunately Tony made a long time in the race, but the next race will take place on September 25th / 25th. Unfortunately already the last of the season and then in Cadwell Park.
“The meeting didn't quite go to plan due to me deciding to test the hardness of the tarmac! (…) Practice was very wet… (…) The damper was set to 3mm pre-sag .. -5max compression and -5max rebound damping. My first impression is that this damper actually works and works very well.
The bike soaks up the bumps pretty well but I feel maybe I could have set the rebound a little harder to help stop the back end bounce on one particular corner. The engine runs a little hot with a little detonation and so I increase carburation to solve this.
By the time of the first race the track is dry. I am on last place on the grid (grid positions are based on previous meeting's results and I couldn't attend). By then end of the lap I am up to 5th from 19 starters, but there is a problem with the bike. (...)
The shock I have set to -3max on rebound and -4max compression .. its working fine and the bike feels transformed. By lap 1.5 I am into 4th behind the 250cc grp6 bikes of Topper, Turner and the 210 grp4 bike of Charely Edmonds. The corner which I had the issue on is now improved and the bike feels much safer and I actually manage to stay on the seat .. the corner is a 70mph left.
On the next lap however the motor cuts and then fires up again whilst banked over on a second gear corner .. This spits me off and into the dirt.
(...) The shock however even in two laps I feel is a massive improvement over the rs24. I feel yes for the track it could do with more damping as I think over the 10 lap race the oil will heat and it may lose damping. It would be nice to have the settings at mid-adjustment on compression and rebound. The spring does touch my tire (3.50 sava) but I can't move the shock over any more at present as the exhaust is in the way. I hope to move this over a little in the winter to solve this problem. the spring rate I would say is correct for me as it is.
During the day lots of racers were interested in the new shock. ”
THANKS TONY !!!!
