Locking the rear wheel easily is not a sign of effectiveness, it actually shows how little you're working with. Weight shift or not, the rear wheel starts out with far less slowing ability than the front before traction leaves the chat. That's why they put two big rotors up front and one little one in back. The worst crashes I've seen involved riders who braked only with the rear and either fishtailed/high-sided or crashed into whatever they were braking for. Maximum braking can only be achieved with the front brake applied, after the suspension compresses which takes a moment. Yes you'll have less from the rear at that point, and that's okay.Understand what is being said concerning the feebleness concerning the rear brakes on a vstrom. I experience that after changing the rear pads. The weakness of the braking is a, "you've got to be kidding", type of joke. The pad eventually wear-in and the rear brakes become usable again.
On my bike, once the rear pad wear-in I'm able to lock the rear wheel on dry, clean pavement, with both MC tires and that CT. Lock it enough so the ABS kicks in and can hear the tire squeal against the road between the ABS pulses. This is with regular foot pressure, not standing up on the rear brake lever.
Someone mentioned the 70/30 mix of braking with 70 percent of braking happening on the front wheel.
The 70/30 ratio between front/back is only true once the front brake is applied, shifting weight from the rear wheel to the front.
When the front brake isn't applied, this weight shift doesn't happen. One has more stopping power on the rear wheel when the front brakes aren't used because there is more weight remaining on the back wheel.
Once the front brake is activated, the bike dives, lifting the rear wheel, the stopping power of the rear wheel is substantially reduced.
Using the rear wheel as a primary source of braking doesn't mean the right hand isn't on the front brake lever when using the rear brake. A rider has to have their hands in position to use both brakes if that is needed.
Aside, watching other riders ride, most of them don't counter steer into their turns, they lean. Where leaning kills riders is entering a turn too fast. They can't lean enough or quickly enough they end up swerving into on-coming lane. When there is on-coming traffic, it is a head on collision.
Counter steering saves a rider on two fronts. It takes speed off the bike without using the brake, a rider has to throttle during the turn to maintain speed. Counter steering allows a rider to make tighter turns compared to leaning.
When riding two up the rear passenger leaning can affect turns where the driver also leans. A passenger's leaning has less effect when the driver counter steers instead of leaning. A passenger leaning can't over come the gyroscopic force of the front tire.
Please do yourself a favor and compare stopping distances at max braking with the rear only versus rear and front combined. This is something that needs to be trained or else you won't react properly when the time comes.
Riders are countersteering to lean the bike whether they realize it or not. Many fail to recognize that it's the pressure on the bar that initiates the bike lean (not their body leaning) in the first place. They either don't piece together or don't trust that pushing harder will tighten up the curve as long as they have the traction and ground clearance. The correct body position helps ensure clearance. It doesn't slow the bike down much, but it does encourage throttling out to stand the bike up for the exit which keeps the bike planted.
