Engine Breaking and Clutch Wear Advice

I had lunch today with five motorcycle buddies (all over 55 and long term riders) and one bud, a Goldwing rider, just had his clutch replaced at 45,000 miles. He told me that I should limit downshifting for braking and use the brakes instead because break pads are a lot cheaper than a clutch. I always downshift to brake (its fun). Any opinions on this issue? My 04 RT had 45,000 miles and no clutch issues. How much does a clutch replacement cost and is this a real issue?

Clutch pack goes for about $800. The basket seems to wear on the new K-bikes as well which is another $800. Replace the throwout bearing, gasket, nonreuseable bolts and the total without labor can be $2000, list price.

I don't think it's an issue, plus a clutch job is a lot cheaper than a trip to the ER.
Stop however you feel comfortable. I do engine brake, no idea what this rocket scientist is talking about, "don't engine brake", yeeesh.

With the high compression of the KGT engine, I get plenty of engine BRAKING (note spelling) in most gears without downshifting. Racing the engine to match rpm's and gears just wastes gas and generates wear. It is fun though and we can pretend we are Valentino Rossi.

How much clutch wear is going to happen in the 3/100th's of a second that the clutch is used to downshift? Every track school I have attended teaches high rpm's and engine braking are your friend when you need to stop. In daily riding I apply the brake sparingly. With 50K miles on the original clutch and brake pads I guess this works for me.

Clutch braking

If the clutch is properly engaged (match revs) and you're engine braking there is minimal clutch wear.

If you are using the clutch to synch the revs to wheel speed that's a different issue.

Besides its fun to blip the throttle on the way down.

If you had a slipper clutch, sometimes it will accelerate wear.

Besides being much smoother, matching engine speed to wheel speed is going to be much easier on the clutch.

Blipping the throttle on a downshift is just basic good riding technique. If you release the clutch in a downshift with a large mismatch between revs and wheel speed, you will unsettle the rear end of the bike, like stabbing the rear brake hard. Not fun on a curve or on slick surfaces. The reduced clutch wear is just the gravy.
