The first thing that came to mind when I took a look at your page was that I would have liked to see the section you have for “Ready to take on any terrain” (with the background image) closer to the top of the page. I think it kind of softens the arrival to the page a bit.
You have two buttons that say “Book a test drive” at the very top of the page (were you looking to make this a sticky bar perhaps?) and then another one beneath the specs for the first bike. I would maybe try changing the copy of one of these buttons so you’re not saying the same thing twice.
I really like the rest of the page though! I think the white space at the top of the page is just a bit jarring - so perhaps you could consider A/B testing some variations of this page where the elements are moved around a bit! Try some different colours too, perhaps!
Hope this helps.
