I've had my 1100s close on 14 years from Dymags to Ti front wheel spindle and god knows what else in between and it's still on going more torque?? out of an 1100cc twin  ,quicker steering,less weight, more HP and quicker and I'm more than happy to put my induct/SJ filter/PC with a custom map anything else,the one thing I know about torque it lets you laugh first,HP lets you laugh last!! |
Chris, you seem remarkably negative about a product you apparently have not experienced, why is that?
I have found absolutely no need to have the BMSK on my R1200 bikes with standard exhausts remapped, waste of time and money as far as I am concerned. All they have needed was the forcing of the slightly richer maps already programed into the ECU. That can be easily achieved with a very simple $10 home made temperature spoofing device. Both bikes pull cleanly and strongly from idle to red line with no issues, noticeably better than standard, especially at lower rpm. More get up and go is available over the majority of the rev range with an imperceptible loss (if any) at the rev limiter. That's ideal for my use as I, like most here I suspect, spend very little time above 7000rpm.
Spend as much time and money as you want on snorkels, air filters, Rapid Bikes or ECU remapping, but you cant equal what the sprockets do as advancing the cam timing fundamentally affects how the engine draws in air.
I have never ridden an R1100, but have owned all versions of the 1200 hex head engines, plus ridden the cam head and water boxer. I dont rate any of them as strong performers below 4000rpm, even compared to big twin Italian super sports bikes that are designed for top end power with far higher rev limits.
Compared to big 4 cylinder bikes like the K1300 the boxer is gutless down low.
BMW obviously figured they needed to improve torque spread as the cam head was a step in that direction and considered to be "better" because of it.
In back to back testing I found my R1200GS hex head with Lennies sprockets very competitive with the cam head GS, it actually felt smoother and stronger down low. The water boxer GS I tested seemed to have only improved in the top end, not very useful IMHO.
