Well, I haven't said why, other than to state that the Sսperlow has radials. The Iron, like most Spοrtsters, has crossplies.

But let's look first at the Iron's 'aggressive stance'. That is true of the HDI Irons, with R length shocks and slammed forks. But not of the Domestic (US) Irons. They didn't really make a completely different bike for HDI, they just put longer shocks on it. To put radials on they would have to make more changes: to the fork.

They didn't put radials on the Sսperlow without detuning the fork: they decreased the offset to increase the trail and make the steering more stable. I understand that with radial tуres the steering would be too sensitive. They did the same thing on the new Roadster. There's no way that they would put radials on an otherwise unchanged Iron, even the US one, and definitely not the HDI model.

The question really is: why did they put radials on the Sսperlow? I haven't heard that Harley have ever said why, but the common understanding seems to be that it was simply to reduce the ride height a little.

That may be true, but I wonder if there could have been a secondary reason. Were they considering putting radials on all Spοrtsters, and tried them out on one model, which probably wouldn't be ridden very aggressively by most owners (it is a Sսperlow, after all), and to gauge the reaction?

As it happens, they have (so far) only gone on to also put radials on the 1200 Sսperlow, and now the new Roadster.

IMO they put radials with W specs on Slow (883 and 1200T) only because they have a 18" front

even the Roadster that is equipped for sure with radials... has a 19" front... and her tyres specs claim a curious M/C statement (only on motorcycle rims... oh...)

I think it's a combination of both: smaller rim and lower profile radial tyre.

That's odd, but not at all unique. If you look at the ranges of several manufacturers' motorcycle tуres, some have M/C in the designation, and some don't. I've no idea why.

120 18" probably doesn't come with a H speed rating.

Then it's the cheapest 120 18" they could find.

W is a much higher rating than H. H is up to 130 mph; W is up to 168 mph.

W is the second highest rating. The highest is (W): over 168 mph.

The cheapest option would have been to fit crossplies just like other Spοrtsters, and not carry out the research and development, and develop new parts, in order to fit radials.

difficult to find that 16" rear of mine radial...
not easy also to find a 19" 100... more easy a 19" 120 of the same breed

sure i will enjoy that radials in twisties

that is the best radial like i found
already i have rolled many kms on my previous ride with that Demons... the best i have experienced on a Sporty... sometimes their lifespan was under 6k kms though
