Hi,

That´s a difficult question, both because no one knows how the weather will be and I drive a 4x4 not a motorcycle.
Second half of april is about the time I change from winter to summer tires. That means most of the snow will be gone and the main roads clear of snow most of the time. But it is very well possible there still will be snowy days. Usually when it snows at night in late april , that snow will vanish at daytime. But as said, it also can happen you have a bad weather front coming over and it can be snowing for a couple of days.

So the question is, can you and your motorcycle handle some snow on the roads? If not, do you have the time to relax for half a day or in worst case a day or rwo?

What I wrote here applies to the main roads. All the small roads and tracks over mountains and in the interior (highlands) of the country are deffinately closed and impossible. Also campsites won´t open before half may. When you like to walk, the paths to most touristic places will be clear of snow or covered in snow. But don´t think about hiking in nature (of the beaten track) because it will be too wet and boggy, marshy.

To summarize: Is it possuble? When you stick to the main roads, yes. Is it comfortable on a motorcycle? I don´t know. I think it is very early in the year and you could either be lucky or unlucky with the weather.
I think you pay a lot of money for a trip to Iceland, spending that much money I would go between late july and half september to get the most out of it.

Best regards,
