Wondering if there's a displacement requirement for the 400 series highways?

I have a ...smaller bike... that's quite capable of highway speeds at least as long as my courage to ride it at that pace will hold out.
 
Naturally aspirated or boosted?
 
The displacement on the plated vehicle must be greater than 50cc (fifty) on Ontario highways. 50 exactly is not allowable. 51 is allowable.

i think 125 is doable if your not a heavy guy but it might be pushing it. 250 should be fine

I am a super lightweight, stuck to the right lane and a CBR 125 on the 400 was still a somewhat frightening experience

125 cc on DVP with tail winds was doing 110 kmph..I was tailing a friend who was on it...

anything >125 cc will be ok ( even 125cc can make it if the rider is courageous eneough!)
 
I used to run a CBX250 up the DVP.....maxed out at 120km/h, so I stayed in the right lane. Modern 250s should be fine though.
 
as long as it can do the maximum speed limit and maintain highway speed, told by MTO. Just use common sense, 50cc is definitely not enough

My MiniTrail should 'hit the wall' at 100 KpH or so - right at the 62MPH max rating of the Bridgestone TrailWings. One short stint from Stanley Avenue to Dorchester on the 420 (one ramp to the next with a backup run for proof on the GPS). Just for bragging rights at Tim Hortons. Beyond that I'll keep it to the secondary highways where it's more fun (IE not 100% pure terror on 10" wheels) to ride.

Lol. 12 N/A HP is a 7 HP jump over stock. 3 point jump in compression ratio, big valve head and a few other tricks ;)

Can you talk about the engine? Is it the rebuilt original? Lifan? Parts sourcing? Thanks:)
 
I've gotten my CBR250RA up to around 163km/h indicated on level ground...at a...erm 'track' of course. Also not really a light-weight at around 165lbs (probably 185lbs with gear).

First year of riding I always stayed away from the 400-series unless riding in a group, but second year I pretty much used it 90% of the time when commuting and not hitting up the back roads up north.

I imagine the DVP would be fine... the 401 even was alright. The 400 moves just enough more quickly that it crossed my arbitrary threshold.

I wouldn't take that little thing on a 400 series in the GTA even if it is only for 1 exit.

Same thought enters my mind every time I turn onto the nearest main road near my house. A healthy dose of terror keeps you on your toes.

There's more than meets the eye here aside from the engine as well. All Balls steering stem taper bearing conversion, fresh forks seals with 20wt fork oil, fresh Trail Wings and tubes, all new drive components, EBC grooved brake shoes; it's really quite stable under the weight of an adult; the rear likes to buck a little bit, I plan to resolve this prior to my 'landspeed' attempt.

I've ridden the cbr125 for 2 seasons and never really had any issues on the highway. Gone for 10+ hr rides - a lot of it on the highway holding 120km/h on flat road and needing to go into full tuck for uphills. The real challenge is overtaking and being aware of upcoming vehicles in the lanes around you.

The answer to your original question: as long as your bike is considered a full-power motorcycle and not limited (small scooters) - and of course road legal..
