VOL. 54 ISSUE 34 AUGUST 29, 2017 P103 Now that Honda has an- other year of testing under its belt, the 2018 comes with new engine mapping. Like last year, there are three pre-programed map settings to chose from, which you can access via a button on the handlebar. Map 1 (the standard map and the one you'll probably use most) has been tweaked for better roll-on power deliv- ery and smoother transition through the rpm range. Map 2 (softer) and map 3 (aggressive) remain the same. That's about it for engine changes, but it does have new upper engine mounts. Over the years, it's been discovered that engine mounts can play a significant role in how a mo- torcycle handles and feels on the track, and Honda says that the new shape of the upper engine mounts are designed to promote more flex, resulting in improved "comfort" for the rider. Honda test riders say that with the new map setting and new upper engine mounts, the Honda has improved power, allows for better overall control and improved traction. Our test riders agree. While the changes Honda made to the CRF450R might seem small—and they are, re- ally—they do make a noticeable difference on the track, and all for the better. During out testing, we got the chance to ride a 2017 model back to back with the 2018 and you can indeed feel the difference in both the power and handling departments. As far as power in Map 1, off- idle, it's similar to the '17 with good engine spin-up, but right after (we'll call it low-midrange or upper off-idle) there's a meaty part of the power deliv- ery that really pulls with control. If It Was Ours… …We wouldn't make many chang- es right away to the 2018 Honda CRF450R. We'd be plenty happy racing it just the way it is. However, down the road, we'd probably look for ways to shed some weight, and an aftermarket single muffler exhaust system might be the best way of doing that. But, handling might be compromised. Honda claims that its dual exhaust system is there to help improve handling. We've experienced some clutch fading with the CRF450R in the past, and since the clutch hasn't changed all that much over the years, we'd also consider beefing it a up bit, and one good way of doing that is giving Hinson Racing a call. (Left top) Dual mufflers are now a Honda trademark. When it comes to improving handling, Honda says two is better than one. (Left bottom) See that seemingly innocent-looking upper engine mount? It's been redesigned to help improve handling. (Right) We love this little button. Electric starting is now standard on the '18 CRF450R.
