I believe this 21st century engine is well engineered and toughened.

That should be true of any production motor, but as an owner of Harleys for almost 30 years, I would not say it would be safe with them. The problem is that the longer the stroke is of a motor, the faster the piston speeds are as the revs climb. "Square" motors with equal bores and strokes can rev higher safely, as can "oversquare" motors where the stroke is less than the bore, keeping piston speeds lower than long stroke motors. With a long stroke motor, a piston has a lot of ground to cover with every revolution of the crankshaft, resulting in very high piston speeds and a lot heat and stress if revs climb too high. Besides the much higher fuel consumption and with stronger motorbikes the too easily been reached risk of your driving license, I don't think it's a good idea to ride a bike near or in its limits, though some may stand this test better than other. The CB is probably one of the better kind. The longer stroke in a RE Bullet is the reason why the manufactor advices the owner not to rev the bike hard for a longer time, because the Bullet is not full speed safe. It's a good idea to stick to this advice. I think it's even a good idea to ride every motorvehicle beneath its highest power to enjoy it over a long time. If something goes wrong with an engine, it is likely the case while riding or driving it too hard or rev it too high. Wisedrum RE: Cruising RPMs - alprider - 04-10-2019 the fifth (sixth) is good for cruising by 30ml/h too or the engine turns round/ smooth too in this area... hey you have not only 2 (big) cylinders !....and if you need temporarily for something much more power and torque/speed so switch some down for any seconds if its not enough only some turn the throttle....so easy is that... or too Get to know the machine at which slopes you really have to switch down only for cruising RE: Cruising RPMs - Skypilot_imp - 04-10-2019 (04-10-2019, 04:37 AM)apex1_imp Wrote: You could probably bounce your CB off the rev limiter all day and not hurt it.

Very nice reply there. Thanks for the good details. So either way I just took her out for good ride at 40 degrees F. Not the nicest day up here but I did play with the revs a once she was warmed up. The gears are mighty tall compared to the Vtwin. Launching in 2nd gear Makes for a nice long wind up to 3rd. Dang this is a fun bike, comfortable ride, smooth and easy shifting. Very happy with the purchase! RE: Cruising RPMs - dbarkdoll_imp - 04-10-2019 Glad to hear that you are pleased so far. It only gets better with time!!

Hope you have fun! My assessment is a giant grin and frozen hands. I stayed out too long in the 40 degree weather here but could not get myself to head home. I took a nice long 10 mile secondary road loop. Twice just for fun. The machine is a magic carpet ride as you said. My original CB was my first bike with nothing to compare to. But after that there was a KZ 1100, a big 1500 Vulcan, and too many Sportsters and Dynas to remember. Not sure why I didn’t go back to an I-4 Earlier. So long story short, better late than never. Hydraulic clutch? Try getting a 2 finger pull on a Dyna. I was nearly bending the clutch lever for the first 20 minutes until I realized what I was doing. And the throttle is light and crisp. Handling... I have been used to standing on my pegs when I see a bump or service cover coming my way. I confess I was doin the same out of habit until I decided to just see what happened. Not sure yet what the CB doesn’t has for suspension but it absorbs the New England roads like a dream. Leaning into the turns was a piece of cake and felt like I could lean a bunch more if I desired. No nasty front end dive when braking either. Granted my last Dyna weighed in near 675lbs. I think that was DRY weight! RE: Cruising RPMs - the Ferret - 04-10-2019 If you think the gears are too tall, many on the forum who like a more spirited ride go up a tooth on the counter sprocket. More acceration, higher cruising rpms, less top speed. Be sure and check your tire pressures if you haven't already 36F 42 R |
