Default Down shifting to slow down?

I've been riding a sport bike for several years and I'm used to down-shifting, sometimes sort of aggressively, as I approach red lights or other times I need to slow down. I find myself doing the same thing with my new (to me) 04 KP. Should I be on the brakes more or is it safe to down-shift through the gears to slow down? (With the 04 KP) As always thanks for the knowledgeable responses!

There's nothing wrong with downshifting. It's wrong not to downshift. You want the engine's RPM to match your speed, so as you're slowing down, do downshift. Letting the motor give you braking power not only saves the brakes, but ensures you're in the correct gear if you need to get on the gas for an emergency move. Just make sure you don't drop down to 1st gear until you're below 10-15mph.

Please add your bike's year and model to your signature. Here's why.

edit: i should start by saying I use this method most of the time... i realize this post made it sound like i was not recommending downshifting to slow down. this is not the case....

Tagging on to what crossroads said, I'd advise that you should rev-match by blipping the throttle to minimize the jerking effect of going down a gear.

More importantly, keep in mind that these big twins have a LOT of engine braking, and can break the rear tire loose on dirty pavement (or worse, gravel). Various conditions can be a poor choice for downshifting to slow down (even when rev-matching).

use good judgement- if you are on a low-traction surface, use your brakes evenly to slow down. Low traction surfaces can be many things in this case: rain, gravel, light sand on surface, GOING DOWNHILL, etc.

be smart, and keep the shiny side up!

Engine breaking can cause oil consumption. I watch friends down shift all the time to slow down or to stop and they add a half a quart to a full quart between oil changes.

"Engine braking" was brought up in our MSF class. I've used it since day one with the exception of wet or sandy roads.

Johnny's post showed up same time as mine... I haven't had an oil loss issue in my experiences on three different bikes.
Anything's possible though, maybe a bike with higher mileage might have some blow-by.

If a bike is chewing that much oil between changes, I'd say the problem is likely more than just engine braking. Probably not broken in well and have a lot of blowby.

I rarely downshift. Just use the brakes. When I come to a stop sign, or red light I use the brakes until I get to about 10 MPH and then just shift to either neutral or first gear. It works fine and brakes are easy to change. I think it is your call, but I can't see adding any additional stress to the engine or transmission

isn't going to be a lot more stress than hard acceleration.

Plus I feel it's good to put the cylinders under vacuum every now and then.

Thanks for the responses, I'm used to rev-matching and what not and being careful on low-traction surfaces so that's not a problem, was more interested to see if the same method is used with these cruisers as is used with the crotch rockets I'm used to - thank you for enlightening me!

As was already covered... yes, engine braking is the proper way to slow down in combination with your brakes.

Do keep in mind though that unlike a sportbike, you do not have a slipper clutch, so aggressive downshifting should be tempered with aggressive throttle manipulation. While of course you know to blip the throttle to rev-match under normal downshifting, you will need to be more on top of this under an aggressive situation. That ass-end will kick out real fast!
