I took my modern on the VMCC, (Vintage MotorCycle Club) Three Counties run yesterday. The ride covered parts of Warwickshire, Leicestershire and Northamptonshire.
Although the qualifying age of motorcycles for the VMCC is anything greater than 25 years*, the branch secretary gave me permission to bring the new bike. I had a lot of, possibly polite, interest in my bike and some scowls.
The new BSA, (there, I've said it) is still running in so may be stiff but is noticeably less flexible about which gear you are in than my low comp A10. The new bike requires me to be in the right gear for the road speed. When coming into a 30 mph area it's no good leaving the bike in fifth; if I do not change into fourth or even third, it starts to chunter. Riding in convoy with slow moving motorbikes I spent a lot of time changing gear; not so bad when I was on my own riding home as I just had to anticipate bends and speed limits.
The bike is very nice to ride; it has oodles of power. I accelerated away from traffic lights a bit enthusiastically and briefly lifted the front wheel 😣. The brakes are disks so excellent. The riding position is upright so the visibility is good.
*A VMCC ride out is strange because you will see a 1980's Honda riding beside a flat tank pioneer.
“Chuntering” in top gear is def a problem with many moderns, on most the root cause is simply that top gear is “high” due to the top speed of the bike eg a modern geared for 140 mph at 9000 rpm is NOT going to be happy doing less than 2000rpm at 30mph (especially if its a twin). If top is high then due to the 5 or 6 speed box then the gear down will be high as well.
Of all the moderns I have owned the 1800 gold wing requires the least gear changes (6 cylinders with redline at 5500rpm, 115hp, 60mpg) a truly amazing engine (and associated weight penalty), the second most “flexible” was a 675 Triumph (3 cyls) somewhat surprising that but it has a flat torque curve from a bit over 2000 rpm to over 12000rpm. The worst was a 1400 v twin suzuki (harley lookalike) which did not like revving and also did not like going much below 2500 rpm (max power at 5000rpm) so one was constantly changing gear to keep it at an rpm where it was happy, pretty awful to ride really, especially on hilly and/or tricky twisty roads and surprising given the laid back cruiser image those sorts of bikes have.
My 3 BSA’s are “flexible” even the B44, a real pleasure to ride around town or slow tricky roads, bit buzzy at 100k as they are geared low….which helps with the flexibility of course.
So, your comments are interesting to me, flexibility in higher gears is something I would definitely be looking for in any new bike I would look at buying. I am toying with trading my ktm 950 for a new ktm 390 adv single, as its much lighter. The 390 ktm is made in india!
