The Engine

This engine is so different from the engine on the Instead of being a low-end-torque with a big flywheel, the K75 feels it has no flywheel at all. When you the throttle, the familiar sensation of pulling the bike to the right is

When I first started the I thought something might be — there was a high-pitched accompanying the normal engine that was very strange I knew beforehand that whined, I just didn’t it was quite so prominent. The engine actually reminds me very of the Jetson’s hovercars — high-pitched whining putt-putt is exactly the sound of this accelerating slowly away in gear.

Something about engines has always made me disconnected from how it all works. remains true on the K75. it certainly does accelerate

I think this engine has low-end-torque than the R65 though, I’ve … it once the R bike wouldn’t have pulling into traffic time to kill an engine, by the

Starting this engine is much easier than on the although I think that is to be The choke lever isn’t operating a choke so much as a cam on the injector controller. Once started, the engine idles

The Driveline

The path taken by the power, getting from the to the wheel, is essentially the same as on my The clutch on this bike much crisper (although my clutch will feel the way after its replacement) than the and the gearbox feels slightly The one major change that noticed is that the shift now stops in the middle position you’ve hit first gear can’t press it down any

This makes it a bit more when you’ve gone all the way

The gearbox is still fairly with plenty of opportunities (or so it to find false neutrals. I actually found any yet, so I may be the catch I feel halfway the throw. Downshifting feels a bit positive though.

The Brakes

The thing I noticed about the on this bike was the fact the rear brake actually something. Unlike on the R65, I can slow down the entire with the rear brake on the The front brakes feel of weak by comparison, but I can’t if that’s due to the rear brake so powerful, or if it’s that actually weaker than used to.

Perhaps less bite better describe the front — I know they’ll the bike quite well, you have to be more aggressive to do it.


The K75s uses the Monolever suspension, which basically you get one swingarm going back of two. It also means you have one shock and one spring in the — on the particular bike borrowing, the stock shock has replaced with an Ohlins with a remote reservoir. I really comment on the Ohlins as I won’t have time to it properly.

The front suspension is exactly the same as on the R65 — a fork with a spring in leg. The springs on this are stiffer than the R65, is pretty nice for regular but could be improved for going big bumps.

The Dashboard and Fairing

The on this bike is one of the areas of improvement, to me. (Well, ok, the engine is significant, but I’m more of things that are comparable the two bikes.) It has the speedometer and tachometer as expect, but it has two additions that I like: a clock, and an indicator shows which gear in. The clock is pretty much issue, as far as I can tell, but it’s a welcome change from the dash.

The gear indicator is a little LCD display in the lower right of the tachometer — but what a thing! Perhaps I’m showing my neophyte preferences, but I like having an indication of gear I’m in, rather having to calculate RPM vs. speed, or the current gear in mind for a trip. Especially with the engine, it’s very to have.

The downside of the dashboard is (at least on the example I have) not attached very well. over bumps would be except that I’m the instrument cluster is going to off. It wobbles back and and makes disconcerting noises.

hasn’t apparently had a negative on the function of the instruments, but that go on forever.

Riding Impressions

The I rode was a pretty nice It clearly had felt its 38,000 but it wasn’t especially worn It wasn’t as quick to steer as the and was a little bit top heavy, comparatively.

Its engine is clearly superior a riding standpoint. From a standpoint, I’ll stick the old Boxer .

Although I know is a personal thing, I found the fairing and instruments were disconcerting — it felt as the wheel wasn’t moving, and into a turn (turning a driveway onto a street for was difficult. With the fairing and all pointed straight ahead, I was to overcome the fear that the was pointed straight ahead as

This bike also by dislike for regular mirrors bar-end mirrors are far superior for me. I’m too wide or something, but mirrors either show me 45 degrees behind me, or my arms. is particularly useful when to determine if there’s a truck no brakes screaming towards me at a sign.

Bar-end mirrors, on the hand, are wide enough to what’s actually behind me. sure this is a matter of taste, though.

The seating on the K75s surprised me. I had thought I was forward on the R65 LS; boy was I wrong! The K75 had the handlebars at least an inch forward, more, so that I was approaching the tuck.

Getting on the R65 afterwards, I that the K75 felt about a longer in front, mostly due to the reach to the bars, and the fairing, thrusts forward from the

Glossary (Stuff I wish had told me when I was starting)

The Boxer refers to an engine where a pair of cylinders are opposed to each other if you look at the two cylinders from the they’re almost on the same on either side of the engine. they fire, they do so on strokes, but both cylinders in towards the crankshaft and out away the crankshaft at the same time. The at least in theory, is a vibrationless

Notchy shifting

When says a shifter feels they mean that not a silky smooth feeling moving the shift lever one gear to another. It feels like there are notches you to move the lever past in to make a complete transition one gear to another. Usually, if you when you hit one of those notches, find a false neutral.


A motorcycle transmission has 4 or five gears, plus a neutral — a position in the transmission doesn’t power the wheel. This neutral is found between first and gear. When you find a neutral, you’ve shifted the so that the gears aren’t engaged, and it feels like in neutral again: the wheel’s not any power from the engine. this happens between other than first and which is bad.

It usually means that and engaging levers are spinning sub-millimeter clearance between probably doing Bad Things to the This is usually the result of a particularly notchy transition gears.

Bar-end mirrors

mirrors are a style of mirror the most famous is the Napoleon which attaches to the end of a bike’s just like the name The mirror is thus placed out board than anything on the bike (unless you’ve got saddlebags attached), and usually you can see what’s actually behind like with a car’s
